- You can if you're root
- Nobody cares, you're root already
- If you're using SELinux, it shouldn't let you ptrace across contexts
- If you can, somebody needs to fix your policy
- You have no caps to drop if you're not root (via SUID or other)
I think that covers about everything. There's a lot of "well this
situation lets you get away with it" that ends something like "... but
you own the box already anyway."
Bring back the Firefox plushy!
