Su is from an older era and so generally defaults to preserving almost everything (for good or bad, take your pick).
The chances are near zero, and the pro-pardon crowd doesn't seem to be doing anything to cange this. If your goal is to get him pardoned, these are the sorts of things you’ll have to overcome.The tl;dr list is this: Protect Whistleblowers: Often the best source of information about waste, fraud, and abuse in government is an existing government employee committed to public integrity and willing to speak out.Such acts of courage and patriotism, which can sometimes save lives and often save taxpayer dollars, should be encouraged rather than stifled as they have been during the Bush administration.Every so often I want to transfer a root-only file from my office workstation off to another machine for analysis or the like (the reasons this is necessary are complex).So every so often I wind up doing this: prewrap just works without any password challenge.
The first time that this happened I was surprised for a bit, then I worked out what was happening.
What's happened is that I switched to holding my SSH keys in sees that it has a SSH agent available and uses it.
Voila, passwordless access for root to my remote account.
This doesn't happen on our servers because I don't forward my SSH agent to my account on our servers (I consider it too dangerous).
Of course root had just as much access to my keys back in the days of having them sitting unencrypted in .
By default, sudo preserves only a relatively few environment variables and removes everything else, and the SSH agent environment variables aren't among the environment variables that make it through.
