   Is it possible to install slitaz on a partition with btrfs?
   Two packages are installed: btrfs-mkfs, btrfs-prog.
   When I try to install slitaz get an error message:

   20 Preparing target disk...
   Preparing target partition...
   /dev/sda2: The partition will be cleaned...
   Creating mount point: /mnt/target
   mount: wrong fs type, bad option, bad superblock on /dev/sda2,
   missing codepage or helper program, or other error

   I want to get the system restore points. Is it possible to slitaz?

   Maybe install util-linux-mount beforehand?

   Thank you, but the package util-linux-mount is already installed.

   Can you try to format the partition by hand, then mount it with explicit -t btrfs option?

   root@slitaz:/home/tux# mount -t btrfs /dev/sda2 /mnt/target
   mount: wrong fs type, bad option, bad superblock on /dev/sda2,
   missing codepage or helper program, or other error

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

   What is the result of:

   # blkid /dev/sda2

   And/or

   # tazpkg get-install btrfs-progs
   # btrfs check /dev/sda2

   Sorry.
