>Description:
In two cases in the install script, mount can fail when the drive
is already mounted.  There should be an option in mount so that it
can return a non-failure error code even if the requested operation did
not complete, but the end result was correct.

Ie, mount /dev/wd0a /mnt

fails if /dev/wd0a is already mounted on /mnt, but it is clear that
additional operations in the script after the mount operation can
proceed properly.

The two cases where this fails in the install script are:

1)  If the install script is run a second or more time, things are
    still mounted from previous attempts.

2)  If the distribution sets are specified as being located on a
    local drive and that drive can't be mounted since it already
    is mounted.  [I had unofficially asked for a "install from local
    mounted drive" option in install a while ago (I think it's in
    some ports, but not in others)]
