Baitinq 88c9e4f3b0 Meta: Don't depend on sudo for privileged operations
We previously depended on sudo's specific -E flag to keep all the
environment variables when performing a privilege escalation. We now
incorporate the -E flag into the $SUDO variable, allowing for other
privilege escalation binaries (such as doas) to be used (as long as
they preserve the current environment variables).
