I am using the following fstab entry:
/dev/md0 /tmp mfs rw,nosuid,nodev,-s=32m 0 0
And three times now have I seen this during an installworld, both on a UP and
an SMP system running a very recent -current:
===> usr.sbin/pcvt/ispcvt
install -s -o root -g wheel -m 555 ispcvt /usr/sbin
install -o root -g wheel -m 444 ispcvt.8.gz /usr/share/man/man8
===> usr.sbin/pcvt/vgaio
echo:Input/output error
