Try this:

At which point you will lose you login shell.
umm.. you do? julian@jules:csh julian@jules:su Password: jules# stop $$
Suspended (signal) julian@jules:fg su jules# exit julian@jules: ps [...] 760 p6 Ss 0:00.04 csh 762 p6 S 0:00.03 csh julian@jules:exit julian@jules:
where would you expect to see something different from what I'm seeing?
(obviously a POST KSE-III kernel.. upto and including peter's proc/UMA additions)
Prior to KSE one could switch between an su'ed shell and a normal shell at will by using stop $$ and fg.
Some more details: - this happens for csh but not for bash-1.
or csh on my system for that matter
- ktracing everything shows further strange behaviour. ktrace causes a kernel printf "Out of ktrace request objects.". The login shell is not lost immediately. You get a shell prompt, but at least tty echo is broken, and hitting return a few times causes all the shells to exit.
probably some breakage in your local systemm doesn't happen here. Unless it's jhb's ktrace changes (I don;t know if I have them.. probably do.
Is this breakage considered a bug or a feature?
Bug.
