doas is the openbsd people going "sudo is too complex and is therefore insecure". it has a way simpler config and way smaller source. it also may or may not be fully functional on linux at any given time as it likes to use openbsd kernel apis. for instance on linux by default you must supply a password every time you invoke doas, unlike sudo which provides a temporary session for the tty you authenticate against. doas supports such a session on openbsd, but relies on kernel timers, so by default that functionality is disabled in linux.
