#The flatpak seems to work well. The arch package keeps breaking due to
#deps. See boost-libs and then libicuuc.so.76.

Snapshot

I would recommend creating a "working install" snapshot you can roll back to.

# Take a snapshot
zfs list -d 1 enc1/vms
export ZFS_VOL='enc1/vms/Gambox1-z4e0t'
zfs snapshot $ZFS_VOL@manual-$(date --iso-8601)

# Restore a snapshot
zfs list -t snapshot $ZFS_VOL
export ZFS_SNAPSHOT='enc1/vms/Gambox1-z4e0t@init-no-drivers-2025-03-03_05-35'
zfs rollback $ZFS_SNAPSHOT
