[Libguestfs] [PATCH 7/9] Add support for mounting ufs from NetBSD, and fix FreeBSD detection on Fedora 16
From: Michael Scherer <misc(a)zarb.org>
While testing on Fedora 16, I noticed that Linux will mount the disk
without trouble by using automatically ufstype=old, and yet do not
let us read the directories. So we should start directly with usftype=ufs2,
and if it fail, try 44bsd, as used for netbsd and openbsd ( as seen on
http://wiki-static.aydogan.net/How_to_mount_FFS_partition_under_Linux ).
