It's not hosed, you just happen to have both flavors of cygdrive
prefix.  The user mounts always take precedence over the system-wide
ones.  If I were you I'd remove the user cygdrive (since all your other
mounts are system) with "umount -uc" and then change your system
cygdrive to the desired value, presumably "mount -c /cygdrive".

Nope, use { print $2; exit } to print the first one and stop.  You could
modify the regexp to try to match -u or -s but that's a bad idea because
you don't know in advance which one(s) will be present.
