Avoid Recursive Shells

what

• Export SHELL to match the desired shell, rather than the current sudosh shell
• Do not use -s as it causes an unnecessary subshell
• Emulate more closely the behavior of the desired shell (which is why we dropped the --)

why

• When SHELL was set to the current sudosh wrapper shell, it would cause infinite loops for non-login shells (E.g. where a command was passed via ssh)
• Better compatibility with system login shells

Try multiple methods to determine current user

what

• Check USER, USERNAME, and whoami if we cannot call user.Current()

why

• Alpine linux does not implement underlying sys call for user.Current()

Inherit Parent Environment

what

• inherit parent environment
• use default shell to execute shell commands

why

• parent env is rather important because without it, ssh agent forwarding is impossible (e.g. SSH_AGENT_SOCK)

Implement a Shell Wrapper for `sudo`

what

• implement a sudo wrapper that will sudo self

why

• sudo provides built in session logging and ability to restrict commands that are run
• when used as a login shell (e.g. chsh -s /usr/bin/sudosh foobar) you can force session logging for any user upon login
