After upgrading to sys-apps/baselayout-2.0.0_alpha2 on ppc, it would not start anymore because it could not mount /proc and halted. The reason for this is that fstabinfo always prints its usage and exits with code 1. "fstabinfo -m /" prints: -o noatime -t ext3 /dev/hda4 / Usage: fstabinfo [options] ... "fstabinfo -p /" does the same. When the command is invalid (as "-m 0"), this does not happen (no output is produced).
Fixed in alpha3
Works, thanks a lot.
