# Archbox
|
|
Installs Arch Linux inside a chroot enviroment.
|
|
## Why?
|
|
Ever since I'm running some niche distros like Void, Solus, I had a problem finding softwares I need in their not-so-large repositories, also I don't like how flatpak and snap works. so i decided to create an Arch Linux chroot enviroment everytime I distrohop. Why Arch Linux? They have a really, really good repositories, oh and don't mention how big AUR is.
|
|
## Installation
|
|
### Installing Archbox
|
|
It's pretty easy, just run ```install.sh``` as root.
|
|
### Installing chroot enviroment
|
|
Before creating chroot enviroment, edit your username in ```/etc/archbox.conf```, then do :
|
|
```
|
|
sudo archbox --create <archlinux tarball download link>
|
|
```
|
|
### Configuring filesystem automount
|
|
Execute ```/usr/local/share/archbox/bin/archboxinit start``` on boot.
|
|
If you use systemd, you can create a systemd service with this syntax below :
|
|
```
|
|
[Unit]
|
|
Description=Archbox init
|
|
PartOf=multi-user.target
|
|
|
|
[Service]
|
|
ExecStart=/usr/local/share/archbox/bin/archboxinit start
|
|
Type=oneshot
|
|
User=root
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|

|
|
If you don't use systemd, either create your own init service, or create a @reboot cronjob.
|
|
### Removing chroot enviroment
|
|
**IMPORTANT**, Make sure you've unmounted everything in chroot enviroment, if you're unsure which partitions must be unmounted, remove the init script and reboot, then delete the folder.
|
|
### Entering chroot enviroment
|
|
To enter chroot, do :
|
|
```
|
|
archbox --enter
|
|
```
|
|
### Executing commands in chroot enviroment
|
|
To execute commands inside chroot envirotment, do :
|
|
```
|
|
archbox <command>
|
|
```
|
|
for example, to update chroot, do :
|
|
```
|
|
archbox sudo pacman -Syu
|
|
```
|
|
### Optional steps
|
|
You may want to add this if you don't want to run archbox chroot without password :
|
|
#### Sudo
|
|
```
|
|
%wheel ALL=(root) NOPASSWD: /usr/local/share/archbox/bin/archbox,/usr/local/share/archbox/bin/copyresolv,/usr/local/share/archbox/bin/remount_run
|
|
```
|
|
#### Doas
|
|
```
|
|
permit nopass :wheel as root cmd /usr/local/share/archbox/bin/archbox
|
|
permit nopass :wheel as root cmd /usr/local/share/archbox/bin/copyresolv
|
|
permit nopass :wheel as root cmd /usr/local/share/archbox/bin/remount_run
|
|
```
|
|
### Misc
|
|
#### Systemd services
|
|
Use ```servicectl``` command to manage systemd services.
|
|
More info [here](https://github.com/smaknsk/servicectl)
|
|
|
|
To enable service on host boot, in archbox do :
|
|
```
|
|
sudo servicectl enable <service name>
|
|
```
|
|
To start services immediately, in archbox do :
|
|
```
|
|
sudo servicectl start <service name>
|
|
```
|
|
This isn't actually using systemd to start services, rather it parses systemd .service files and executes it.
|
|
#### Lauching apps via rofi
|
|
Instead of opening terminal everytime you want to run application inside chroot, you may want to launch rofi inside chroot, install rofi and do :
|
|
```
|
|
archbox rofi -show drun
|
|
```
|
|
#### Prompt
|
|
If you use bash with nerd font you could add a nice little Arch Linux icon in your prompt, add :
|
|
```
|
|
[[ -e /etc/arch-release ]] && export PS1=" $PS1"
|
|
```
|
|
to your ```~/.bashrc```
|
|
#### Adding enviroment variables
|
|
Edit ENV_VAR in ```/etc/archbox.conf```. For example, if you want to use qt5ct as Qt5 theme, edit it like this :
|
|
```
|
|
ENV_VAR="QT_QPA_PLATFORMTHEME=qt5ct"
|
|
```
|
|
An example with multiple enviroment variables.
|
|
```
|
|
ENV_VAR="QT_QPA_PLATFORMTHEME=qt5ct GTK_CSD=0 LD_PRELOAD=/var/home/lemniskett/git_repo/gtk3-nocsd/libgtk3-nocsd.so.0"
|
|
```
|
|
### Known issues
|
|
#### Musl-based distros.
|
|
Although /run is mounted in chroot enviroment on boot, XDG_RUNTIME_DIR is not visible in chroot enviroment, remounting /run will make it visible. do :
|
|
```
|
|
archbox --remount-run
|
|
```
|
|
after user login, Also if you use Void Musl, you need to kill every process that runs in XDG_RUNTIME_DIR when you log out, if you use ```startx``` you need to reinstall archbox with ```--exp``` flag and use ```startx-killxdg``` instead of ```startx```.
|
|
Tested in Void Linux musl and Alpine Linux.
|
|
|
|
#### Polkit
|
|
```pkexec``` is kind of tricky to make it work in chroot, if you use rofi to launch GUI applications in chroot, you may not able to launch any ```.desktop``` files with ```Exec=pkexec...``` in it. If you really want them to work, you can do :
|
|
```
|
|
sudo ln -sf /usr/bin/sudo /usr/bin/pkexec
|
|
```
|
|
in chroot and prevent pacman from restoring ```/usr/bin/pkexec``` by editing ```NoExtract``` in ```/etc/pacman.conf```.
|
|
|
|
#### No sudo password in chroot by default.
|
|
You could use ```sudo``` in archbox, but you'll have no way to enter the password when doing e.g. ```archbox sudo pacman -Syu```. also you could enter the password if you do ```archbox -e < <(echo $COMMAND)```, but that would disable stdin entirely during $COMMAND.
