[19:20] <flyback-> 22.04 gives you the option of automatic partitioning and will setup luks for you.   However it chooses ext4 for / and no option to change that.   If you use manual partition you can choose whatever filesystem but then you have to manually setup luks.  Any way to tell the installer to do automatic partitioning with btrfs instead of ext4
[19:52] <wxl> flyback-: untested but perhaps changing defaultFileSystemType in /etc/calamares/modules/partition.conf from ext4 to btrfs might work
[19:52] <wxl> to be clear, exit the installer, make the above change, then rerun the installer
[20:13] <flyback-> oh ok, thx
[20:22] <flyback-> this looks good, I will try it as soon as I get home
