What I observed was that the “fsck -y” would give the “please re-run” message, exit with 0 status so the boot would continue, the subsequent mount would fail because the filesystem was not clean, and *then* the boot would stop and drop to single user. I think my problem is specific to SU without journaling. The UFS code allows one to mount an unclean filesystem in that configuration since SU guarantees that on-disk metadata is consistent. A background fsck takes care of leaked inodes and data blocks. (FWIW, I'm not using journaling only because makefs(8) doesn't support the creation of SU+J filesystems.) /dev/gpt/rootfs: FREE BLK COUNT(S) WRONG IN SUPERBLK (SALVAGED) /dev/gpt/rootfs: SUMMARY INFORMATION BAD (SALVAGED) /dev/gpt/rootfs: BLK(S) MISSING IN BIT MAPS (SALVAGED) /dev/gpt/rootfs: 32664 files, 495447 used, 813272 free (176 frags, 203274 blocks, 0.0% fragmentation) ***** PLEASE RERUN FSCK ***** WARNING: /: reload pending error: blocks 192 files 3 Unknown error 16; help!
