mpd + ncmpcpp

Yes! Awk is great, I use it all the time for text processing problems that are beyond the scope of normal filters but aren’t worth writing a whole program for. It’s pretty versatile, and you can split expressions up and chain them together when they get too complicated. Try piping the output into sh sometime. It can be messy though and my awk programs tend to be write-only

Yeah for me it’s been great and I do essentially leave it plugged in the whole time I’m using my PC (attached to my keys). It does require a pin entered each boot, so leaving it in would still offer security. But as someone else mentioned getting kwallet PAM working would make things easier in any case

Lol. I press a button on the device (which I unlocked with a pin before boot), but it would be nice to have the DB unlock automatically

Personally, I’ve relied on an OnlyKey for a few years (with backups and an extra fallback device) and haven’t needed to type passwords since. This doesn’t help with the number of prompts, but it does make them easier to dismiss.

I do use autologin, but I don’t use a system wallet (only KeePassXC, which I do need to unlock manually). Autologin with system wallets can be tricky, but I’ve had some luck setting it up in the past. You might want to check out this wiki for PAM configuration.

Nice, sounds pretty cool. FZF is great, I need to try out some new things with it. Never got into snippets but I’m sure that speeds things up considerably, will think about it.

Yeah separate config files is probably the best approach if you have a lot of things configured. I haven’t done that yet, but might try soon. My config has generally been pretty simple, mostly bindings and plugin settings. But I started developing in the TTY and had to shoehorn-in a conditional theme and such to get it to work properly, leaving it pretty unorganized.

| I can never leave vim. It has taken over the pathways in my brain.

Haha, yeah

My neovim config is a total mess :D. But yeah i3-msg+jq is great, I’ve written a number of solutions to this problem before using the API and external scripts, but it’s nice having things inline in the config file

For a while I would have agreed, and I used sway for years. But recently I switched back to i3 (i3-rounded) due to display issues with my AMD GPU. I started doing most of my development in the TTY, and found that switching from TTY to Wayland takes half a second and can sometimes break my GPU (until I switch between TTY and display a few times). With X11 it’s instant and without issue ¯\_(ツ)_/¯. Hoping that gets fixed down the road, or that it’s specific to my GPU.

This is always the first thing I get set up:

# focus next available workspace on this output

bindsym $mod+q exec --no-startup-id ws=$(i3-msg -t get_workspaces | jq ‘.[] | select(.focused) | .num’) && ofs=$(i3-msg -t get_outputs | jq ‘map(select(.active)) | length’) && i3-msg workspace $(($ws-$ofs))

bindsym $mod+w exec --no-startup-id ws=$(i3-msg -t get_workspaces | jq ‘.[] | select(.focused) | .num’) && ofs=$(i3-msg -t get_outputs | jq ‘map(select(.active)) | length’) && i3-msg workspace $(($ws+$ofs))

# move window to next available workspace on this output

bindsym $mod+Shift+q exec --no-startup-id ws=$(i3-msg -t get_workspaces | jq ‘.[] | select(.focused) | .num’) && ofs=$(i3-msg -t get_outputs | jq ‘map(select(.active)) | length’) && dest=$(($ws-$ofs)) && i3-msg move workspace $dest && i3-msg workspace $dest

bindsym $mod+Shift+w exec --no-startup-id ws=$(i3-msg -t get_workspaces | jq ‘.[] | select(.focused) | .num’) && ofs=$(i3-msg -t get_outputs | jq ‘map(select(.active)) | length’) && dest=$(($ws+$ofs)) && i3-msg move workspace $dest && i3-msg workspace $dest

Works with sway if you replace i3-msg with swaymsg (and remove --no-startup-id, since it’s not needed for Wayland).

Edit: ampersand issues, trying quote instead of code block

I use LUKS-encrypted LVM volumes to store everything (and transfer via SSH or HTTPS), but would use GPG if I needed to encrypt individual files.

Ah good to know! Will try that if I ever run into issues, thanks

I’ve been using it for years and I think it’s great. Currently on a 6 Pro. It’s true that some apps don’t work without Google Play services, but GrapheneOS has the option to install the google stuff in a sandbox, so you shouldn’t run into any issues if you do that. Personally, I don’t use Play services unless I need to, and use Aurora store for any apps that aren’t on F-Droid.

In any case, you can always revert to stock or try another OS

Edit: as faede has pointed out, it appears that Google Wallet has issues. Also, the usage docs mention issues with banking apps in general, so that’s something to consider

If you’re willing to spend the time to learn how to write custom policies, SELinux can be used for this, to some extent. It’s highly customizable and can sandbox your apps, but the process of doing so is quite complicated. I wrote a small guide on custom policy management on Gentoo in another comment if you’re interested.

There’s also apparently a “sandbox” feature, but I don’t know much about it. I just write my own policies and make them as strict as possible.

As an example, my web browser can’t access my home directory or anything except its own directories, and nobody (including my own user), except root and a few select processes (gpg, gpg-agent, git, pass) can access my gnupg directory.

This only covers security/permissions, and doesn’t include many of the other benefits of containerization or isolation. You could also try KVM with libvirt and Gentoo VMs; that works pretty well (despite update times) and I did that for a while with some success.

np! Hope it helps; it’s a big pain but I do think it’s pretty secure if configured correctly

Awesome! Here are a few things that come to mind:

Make sure you have some aliases/functions for common operations:

• audit2allow -a to view audit violations (or -d for dmesg audits)
  • also -r to add a requires statement for module construction
• restorecon -Rv to recursively apply file contexts from policy (or -FRv to also apply user context)
• rm -f /var/log/audit/audit.log.*; >/var/log/audit/audit.log to clear audit logs
  • note: sometimes lots of logfiles (audit.log.1, etc.) collect, slowing down audit2allow
• chown -R user:user PATH; chcon -R -u user_u PATH to recursively change labels to user
  • could be generalized for arbitrary Linux/SELinux users
• semanage fcontext -a -t TYPE PATH -s $SEUSER to add a custom file context to the policy
  • e.g. semanage fcontext -a -t "user_secrets_t" "/home/[^/]+/.secrets(/.*)?" -s user_u
  • I’ve had better luck with this approach than the standard method of creating a .fc file, but in any case a custom policy is needed to create custom types
• semanage fcontext -d PATH to remove a custom file context
• semanage fcontext -lC to list custom file contexts
• semodule -DB to rebuild policy with all dontaudit rules disabled
  • often, something will not work, but audit2allow doesn’t show anything
• semodule -B to rebuild policy (with dontaudit rules)
• semodule -i MODULE.pp to install a module
• semodule -r MODULE to remove a module

Also a few scripts for policy creation and management are essential. There are two basic approaches to policy creation: modules and policy modules.

Modules: can be used to modify AVC rules and are pretty simple

# a violation has occurred that you want to allow or dontaudit
echo "module my_allow 1.0;" > my_allow.te
audit2allow -ar >> my_allow.te

# verify that my_allow.te has what you expect
cat my_allow.te

# build and install the module (replace mcs with whatever policy you are using)
make -f /usr/share/selinux/mcs/include/Makefile my_allow.pp
semodule -i my_allow.pp

# clear audit logs
rm -f /var/log/audit/audit.log.*; >/var/log/audit/audit.log

Policy modules: can do anything, but are complicated, and the tools for creating them are mostly based on Red Hat.

Creating a new type:

# generate foo.fc, foo.if, and foo.te
sepolicy generate --newtype -t foo_var_lib_t -n foo

# note: see sepolicy-generate(8); sepolicy generate only supports the following
#       type suffixes, but its output files can be adapted to your use case
# _tmp_t
# _unit_file_t
# _var_cache_t
# _var_lib_t
# _var_log_t
# _var_run_t
# _var_spool_t
# _port_t

# modify the .fc file with the desired file contexts, for example (with s0 for mcs)
# /path/to/context/target	--	gen_context(system_u:object_r:type_t,s0)
#
# note: the "--" matches regular files, -d for directories, -c for character
#       devices, -l for symbolic links, -b for block devices, or can be omitted
#       to match anything. also, as mentioned before, I often have better luck
#       with `semanage fcontext`, especially for user directories
vi foo.fc

# build and install the policy module
make -f /usr/share/selinux/mcs/include/Makefile foo.pp
semodule -i foo.pp

# use restorecon to adjust the file contexts of any paths you have 

# by default, all operations involving this type will be denied
# (and are sometimes not audited)
semodule -DB # --disable_dontaudit
# ... use the type, collect violations ...
audit2allow -ar >> foo.te
# if dontaudit is disabled, you'll likely have a lot things to remove from here
vi foo.te

# ... repeat until rules regarding type are fully defined

Creating a new application type:

# sepolicy-generate is made for Red Hat,
# but you can use --application to get started

# creates a bunch of files that define bar_t and bar_exec_t
sepolicy generate --application -n bar [-u USER] CMD

# remove the line making the app permissive (up to you, but
# I prefer using audit violations to define the permissions)
perl -i -00 -pe 's/^permissive bar_t;\n\n//g' bar.te

# ensure that the file bar_exec_t file context points to the right bin:
vi bar.fc

# build and install the policy module
make -f /usr/share/selinux/mcs/include/Makefile bar.pp
semodule -i bar.pp

# ... use the application, update AVC rules, repeat ...

If your target application is interpreted, you’ll need to write a custom C program that launches the interpreter in a specific context, then write your policy around that application. For example, you should execv something like this: /usr/bin/runcon -u user_u -t my_script_t /bin/bash PROG.

Totally, props on taking it on as your first distro! Haha, yeah a week of pain sounds about right. My last Gentoo setup took an entire month (off and on), but I was doing something crazy (Qubes-like, every application in its own Gentoo VM, strict SELinux on host and guests)… ended up ditching that because I got comfortable enough with SELinux to write stronger policies for everything important, which is good enough for me.

I had the benefit of using other distros before trying Gentoo, so my first attempt at it wasn’t so bad (but still took two full days). It’s definitely taught me way more than any other distro, including Arch (although Arch was a very good stepping stone). I don’t think I could go back to anything else at this point

Yep! Gotta love the flexibility of it

Ah gotcha, just asking because I’ve never used it before. Good to know that Gentoo supports hardening it

Oh good to know! Thanks for the tips. What do you like about musl over glibc?

I would look into Gentoo’s Hardened + SELinux profile if you want good security in a standard system, but as others have mentioned QubesOS is probably the most secure option OOTB (but it is very limiting). SELinux is pretty difficult to use but it’s really effective, and there is good information about it on the Gentoo wiki. Not sure what exactly goes into their hardened profile but I know it implements at least some of the suggestions listed on that site (like hardened compilation flags). Also it’s probably more vulnerable to 0-day attacks than Qubes, since it uses up-to-date software. But it’s really flexible, and learning SELinux is useful
