Thanks to those who responded to my question regarding the
su: no shell problem. The solution, thankfully, was simple.
I had checked directory permissions down through /usr/bin/sh
but had neglected to notice that '.' and '..' (ie, /) had
lost their world search privledges, not 0755.

I had this one a while back. Are you sure the permissions are
correct? My problem was that a directory in the path (/) had
"lost" (!) its "search" permisssion (aka execute bit).
I solved that one by trussing 'su', and seeing that execlp (if I
remember correctly) was returning EACCESS. The execlp man
pages describes the situations where this error is returned.

When not specified the default is /bin/sh.

Have you check to make sure there is no /etc/nologin
file?

You should verify the ownership of /. It sould be own by root and the group
should also be root. Also, the protection should be 755.
I had the same problem last week-end. Your problem is that when
/etc/rc2.d/S21perf is doing a su -c sys ..., / is not own by root, so
su ... fails.
