All looks good. I did notice two small things:
1. Your new code no longer outputs "soft-updates, journal" from mount(8) e.g.
old code: /dev/ad8s3d on /export (ufs, NFS exported, local, soft-updates, journal)
new code: /dev/ad8s3d on /export (ufs, NFS exported, local, soft-updates)
If you are not planning to keep the "journal" label in the output of mount(8) is
there any other mechanism to verify that a fs has actually got SUj switched on ?
(this seems to work actually: #dumpfs /dev/ad8s3d | grep -i journal).
2. dmesg(8) displays this upon bootstrap:
WARNING: /export: GJOURNAL flag on fs but no gjournal provider below
I have done at least 4 ALT_BREAK_TO_DEBUGGERs' (~^B) -> reset ... no probs
