Well, yes, as you have seen, I created root.cell volume, made RO copy of it,
made few afs users, have made mounpoints for few volumes. Everyhting went smoothly
until I wanted to shutdown afs.

Well that's what happened. I tried -shutdown but it complained, so I tried umount
but was in /afs/......, so on the third trial I wasn't using the /afs
tree and then it segfaulted.
