replacement for old /etc/mtab that lists only real filesystems like ext4 or fat

[Jan Gregor <gregor.jan@gmail.com>]

Hello,

  I used /etc/mtab to list mounted filesystems with their mount options. Unfortunatelly /etc/mtab no longer exists in debian jessie, it is just symlink to /proc/mounts that lists 31 filesystems and I want to see just 2 :-)  classic filesystems like ext4, fat, btrfs only.

Thanks,

Jan
