new mount regression

new mount regression

[Alexey Gladkov]

Greetings!

I found that mount no longer understands fstype list in the /etc/fstab
after the migration to libmount:

$ dd if=/dev/zero of=/tmp/disk bs=1M count=10
$ losetup /dev/loop0 /tmp/disk
$ mkfs.ext3 /dev/loop0
$ grep loop0 /etc/fstab
/dev/loop0 /media vfat,hfsplus,ext4,ext3,ext2 defaults 0 0

$ mount /media
mount: unknown filesystem type 'vfat,hfsplus,ext4,ext3,ext2'

But if we use deprecated mount:

$ ./mount.deprecated -v /media
/dev/loop0 on /media type ext4 (rw)

Also new mount understands fstype list in options:

$ mount -t vfat,hfsplus,ext4,ext3,ext2 /dev/loop0 /media

Already reported with a patch in
http://marc.info/?l=util-linux-ng&m=134876452206541
The patch was labelled a hack and rejected in
http://marc.info/?l=util-linux-ng&m=134910609108013
but no better alternative is available so far.

Please apply that patch in Sisyphus until upstream has a better fix
for this regression.

 I have applied the Gleb's patch as I did not found a better
 (less invasive) solution.

 Thanks!
