mountd was failing to start after an upgrade, with lots of log entries like: Jun 17 10:19:22 <daemon.err> pointyhat mountd[855]: bad exports list line /a/portbuild/i386/20090421213917 Jun 17 10:19:22 <daemon.err> pointyhat mountd[855]: bad exports list line /a/portbuild/i386/7-exp/builds/20090422073914/src Jun 17 10:19:22 <daemon.err> pointyhat mountd[855]: bad exports list line /a/portbuild/i386/8-exp/builds/20080814181849/ports These came from /etc/zfs/exports, and refer to filesystems that used to exist & were exported, but which have been destroyed. These were not cleaned up at destroy time. zfs unshare -a didn't clean this file up either, I had to remove it and recreate. Also, mountd was treating these as fatal errors at runtime and failing to start. I think this is a recent change in mountd, since this used to work even with the stale entries (the 200808 filesystem was destroyed in 2008, and mountd has started correctly after numerous reboots until the upgrade I just did from a May 9 world+kernel).
