Just like Firefox embarrasses me regularly with its (well, well-intentioned) "this is embarrassing"-message(1), my aesthetic sensation gets regularly confused by Slim's login screen, telling me howto man - every morning anew. (More general argumentation below.)

This would transport approximately the same information ( "this program is named slim" , "it is configurable" , "there is a manpage" ), while not bugging the (AFAIU targeted) experienced sysadmin with too obvious "good advice" - a user who doesn't know themancommand, most likely wouldn't understand the instructions in place anyway.

That's it: My first Devuan being-bug-ed report!
