### Accessing UEFI setup without key smashing

- systemd: there is a `systemctl reboot --firmware-setup`

- Windows allows access to UEFI by pressing Shift while reboot
|

([said here](https://sauna.social/@halva@wetdry.world/113011439141055477)) or
|
||||
simply `shutdown -r -t 1 -fw` twice
|
||||
([said here](https://infosec.exchange/@jernej__s/113012094181641667)).
|
||||
- GNOME: in the reboot after 60 seconds menu, hold alt to get into boot options
|
||||
([said here](https://chaos.social/@keywan/113012020348714057))
|
||||
- In boot loader the command `fwsetup` should take you there
|
||||
([said here](https://fedi.absturztau.be/notice/AlGqYz5GeJOQw9dfNo)). And
|

anyone using either grub or systemd-bootd has probably seen the menu entry.

- Test on Lumina: 20G free -> 24G free.
|
||||
- The compression will happen either the next time the file is written or can
|
||||
be manually triggered through `sudo btrfs filesystem defragment -r "$PWD"`
|
||||
- For swapfiles on btrfs partition, e.g.
|
||||
`btrfs filesystem mkswapfile --size 8G /swap`
|
||||
|
||||
### Swap
|
||||
|
||||
Zramswap is not enough. 8 GB everywhere may be enough,
|
||||
[summarizing Gentoo](https://wiki.gentoo.org/wiki/Handbook:AMD64/Full/Installation#What_about_swap_space.3F).
|
||||
|
||||
No swap partition and swap file is acceptable (consider SSD)? See above for
|
||||
btrfs or as root
|
||||
|
||||
```bash
|
||||
fallocate -l 8G /swap
|
||||
chmod 600 /swap
|
||||
mkswap /swap
|
||||
swapon /swap
|
||||
```
|
||||
|
||||
The `/etc/fstab` rule is: `/swap none swap sw 0 0` and then it's
|
||||
just a matter of `sudo swapon -a`
|
||||
|
||||
### sudo
|
||||
|
||||
- https://codeberg.org/Aminda/shell-things/src/branch/cxefa/etc/sudoers.d
|
||||
|
||||
Consider these:
|
||||
|
||||
```sudoers
|
||||
# Thanks Tails
|
||||
Defaults timestamp_timeout=0
|
||||
Defaults pwfeedback
|
||||
Defaults lecture = always
|
||||
```
|
||||
|
||||
Additionally Arch Linux should consider either
|
||||
|
||||
```sudoers
|
||||
# Allow full sudo access to the group which is uncommented. The first is
|
||||
# Debian.
|
||||
#%sudoers ALL=(ALL:ALL) ALL
|
||||
# Defaults to passwordless sudo on Debian.
|
||||
#%wheel ALL=(ALL:ALL) ALL
|
||||
```
|
||||
|
||||
### Debian
|
||||
|
||||
Remember to install `apt-transport-tor`!
|
||||
|
||||
#### sources.list
|
||||
|
||||
The mirror to use is `https://deb.debian.org/debian`.
|
||||
|
||||
#### `/etc/apt/preferences.d/whatever`
|
||||
|
||||
```apt
|
||||
# Copied from https://www.wireguard.com/install/ (2020-01-11)
|
||||
# Default priority appears to be 500, so 90 results to unstable being
|
||||
# used when the package is not available anywhere else
|
||||

Package: *
|
||||
Pin: release a=unstable-debug
|
||||
Pin-Priority: 90
|
||||
```
|
||||
|
||||
### sshd
|
||||
|
||||
If nothing else, **_please_** at least
|
||||
|
||||
```
|
||||
# ssh-keygen -t ed25519 -N "" -f /etc/ssh/ssh_host_ed25519_key

|
||||
|
||||
### `/etc/xdg/autostart`
|
||||
|
||||
Not having terminal autostarting for all users is pain.
|
||||
|
||||
- https://codeberg.org/Aminda/shell-things/src/branch/cxefa/etc/xdg/autostart/kgx-tmux.desktop
|
||||
|
||||
```desktop
|
||||
[Desktop Entry]
|
||||
Terminal=true
|
||||
Exec=kgx --command="bash --norc -c tmux"
|
||||
Name=Tmux in Console
|
||||
Icon=org.gnome.Console
|
||||
```
|
||||
|
||||
### `aminda-*.{service,socket]`
|
||||
|
||||
They workaround either me or the distribution messing things up. While at it,
|
||||
don't forget `/etc/sysctl.d`
|
||||
|
||||

|
||||
it.
