Install slitaz on btrfs

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?

Re: Install slitaz on btrfs

Maybe install util-linux-mount beforehand?

Re: Install slitaz on btrfs

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

Re: Install slitaz on btrfs

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

Re: Install slitaz on btrfs

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.

Re: Install slitaz on btrfs

What is the result of:

# blkid /dev/sda2

And/or

# tazpkg get-install btrfs-progs

# btrfs check /dev/sda2
