[Libguestfs] [PATCH] build: Choose a virtual directory for the daemon which is not a symlink.
From: "Richard W.M. Jones" <rjones(a)redhat.com>
Check /sbin, /usr/sbin, /bin and /usr/bin to ensure that neither the
directory nor the parent (eg. /usr) is a symlink, and use this
directory for the virtual directory used to store guestfsd in the
appliance.
