Current dailies fail upon mounting ext4 filesystems just after partitioning
(default whole-disk) with the following message:
The attempt to mount a file system with type ext4 in SCSI3 (0,0,0), partition #2
(sda) at / failed.

dmesg says:
ext4: Unknown symbol pagecache_isize_extended (err 0)

Changing the fs type to btrfs (and likely others) allows proceeding.
