It's casued by the check in fs/exec.c that we can't start
a suid process if we're traced and not root. Samba changes
uid to the user doing the printing before firing off lpr,
which catches the problem.
Two questions:
- Would it be better to just turn off tracing in such a situation
rather than alter program behaviour?
- Shouldn't the test be against the permissions of the tracing
process, not the process being traced?
Anyway, it led me on a wild goose chase for a while, and I'm not sure
if the current behaviout is a Good Thing. Comments?
