[PATCH] ver_linux: util-linux_mount.patch

[PATCH] ver_linux: util-linux_mount.patch

[Alexander Kapshuk]

The current implementation relies on 'fdformat' to output the version of
'util-linux'. This does not seem to be reliable, as 'fdformat' is not
available across all ditros these days.

The proposed implementation uses 'mount', which is a part of
'util-linux', to output both the version of
'util-linux' and 'mount' proper. It also used 'sed' for text processing
instead of a combination of 'awk' and 'sed'.



Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
