OK, we progress. The label change fixed it on two of the three machines
I'm having the problem with. On the other, starting it up in selinux
permissive mode (after the relabelling and subsequent reboot) causes
gdm3 to respawn continually. I'll try another strace session on that one
to see if that turns up anything, but I can't get to the machine until
next week (it's my work machine).

Thanks,
