Subject: appliance: Set $PATH instead of hard-coding paths to binaries everywhere.
X-Git-Tag: 1.0.88~4
X-Git-Url: http://git.annexia.org/?p=libguestfs.git;a=commitdiff_plain;h=9e0b31a2af26b8d58a44dd80993a5e73d4942307

appliance: Set $PATH instead of hard-coding paths to binaries everywhere.

Change the appliance so PATH includes common directories.  Thus
we don't need to hard-code paths to binaries (eg. "/sbin/fdisk")
everywhere.
