### Why this
|
|
|
|
If you want to install Archlinux on ZFS, you need to deal with the [ZFS licensing problem](https://wiki.archlinux.org/index.php/ZFS). The kernel module isn't included in the default archiso image, you need to [include it](https://wiki.archlinux.org/index.php/ZFS#Embed_the_archzfs_packages_into_an_archiso) into a custom archiso image to be able to install ZFS.
|
|
|
|
I wrote an article about [archiso netbooting](https://eoli3n.github.io/archlinux/2020/04/25/recovery.html).
|
|
This script lets you include the zfs kernel module on any archiso image without creating a custom one.
|
|
|
|
### Archzfs
|
|
|
|
The [Archzfs](https://github.com/archzfs/archzfs/wiki) unofficial user repository offers multiple ways to install the ZFS kernel module.
|
|
We can install precompiled module with ``zfs-linux`` package or compile the zfs module using [DKMS method](https://wiki.archlinux.org/index.php/ZFS#DKMS).
|
|
In order to build the module, DKMS needs the ``linux-headers`` package for the running kernel.
|
|
|
|
### How does it work
|
|
|
|
It extracts running kernel version and try to find a matching ZFS module in ``Archzfs`` repositories.
|
|
If it doesn't, it fallbacks to the DKMS build of the ZFS module.
|
|
In that case, the script uses [Arch Linux Archive](https://wiki.archlinux.org/index.php/Arch_Linux_Archive#How_to_restore_all_packages_to_a_specific_date) to install the ``linux-headers`` package required for DKMS.
|
|
|
|
### How to use
|
|
|
|
Boot on any archiso system, and run:
|
|
```
|
|
$ curl -s https://eoli3n.github.io/archzfs/init | bash
|
|
```
|
|
|
|
### Debug
|
|
|
|
To run the script in verbose mode, use:
|
|
```
|
|
$ curl -s https://eoli3n.github.io/archzfs/init | sed 's- &>/dev/null--' | bash &> debug.log
|
|
```
|
|
|
|
### Dev
|
|
|
|
```bash
|
|
$ loadkeys fr
|
|
# In pacman.conf, comment SigLevel line
|
|
# Set "SigLevel = Never"
|
|
$ pacman -Syy git
|
|
# In pacman.conf, restore Siglevel line
|
|
```
