FreeBSD 2.0-BUILT-19950512 #395: Fri May 12 14:53:28 EDT 1995
>Description:
1) Fix bug in mount_umap that will be committed after freeze is lifted.
2) mount_umap -u /tmp/uidfile -g /tmp/gidfile /tmp /tmp
This ought to insert a `umap' layer into the existing UFS structure
under /tmp. Instead, I get a `panic: ufs_ihashget: recursive lock
not expected -- pid %d'. Unfirtunately, I didn't save the core
dump, so I can't provide a traceback.
/tmp is on the root filesystem on my machine.
