Callum, >> Did you create the /dev/pts/* devices before the testsuite run? > No, I wasn't certain how to do it. Do I just need to run /dev/MAKEDEV? unfortunately not: those devices are supposed to be created by /usr/sbin/mkpts, as described in getpty(3). I have no idea why this doesn't happen, but you'll have to do it manually as root, using mknod: # cd /dev/pts # mknod <N> c 15 <N> # chmod 620 <N> # chown <user> sys for all missing N (I've created them up to 127).
