Let us build the most complex iso with many resources for the packages.
- Arch Linux
- local repo
We explain the local repository.
You can be in full control. All you need is Arch Linux and Calamares.
Just because we can and just for the fun we change our standard filesystem from ext4 to ext3 and later to ext2.
sudo nano /usr/share/calamares/modules/partition.conf
Other options might be btrfs, jfs, xfs and reiser.
Restart Calamares with calamares_polkit -d.
