Is btrfs subvol support failing just for me? Looks like nothing adds the
required '@/' string. virt-ls uses the first variant of the command:
><rescue> mount -vo subvol=var/spool,ro /dev/sda2 /sysroot/
[ 113.852047] BTRFS info (device sda2): disk space caching is enabled
[ 113.852869] BTRFS: has skinny extents
mount: mount(2) failed: No such file or directory
><rescue> mount -vo subvol=@var/spool,ro /dev/sda2 /sysroot/
[ 116.082642] BTRFS info (device sda2): disk space caching is enabled
[ 116.083476] BTRFS: has skinny extents
mount: mount(2) failed: No such file or directory
><rescue> mount -vo subvol=@/var/spool,ro /dev/sda2 /sysroot/
[ 123.995343] BTRFS info (device sda2): disk space caching is enabled
[ 123.996238] BTRFS: has skinny extents
mount: /dev/sda2 mounted on /sysroot.
><rescue> exit
fstab is:
