No :(
Did a rawhide update (kernel + selinux stuff), touch ./autorelabel,
reboot -> bang
Tried the previous working kernel -> bang
Rebooted on the rescue disk, nothing in the system logs (crash too early
at selinux init)

Since the last sync was only selinux-related, decided to try
selinux=false before mucking with the system, and everything booted at
once.

Will try to reproduce now, in case it was a transient problem
