Comment 4 for bug 68274

Hmm, I'd be very surprised to boot a machine into "single" user mode and find that I've opened myself up to remote ssh login's, giving potentially other people (not me in front of the console) remote access to the system. Single user mode is generally intended for infrequent maintenance, and traditionally by the administrator in front of the console.

I have two suggestions...

1) Look into some of the remote console hardware solutions or hypervisors for virtual machines.

2) If remote ssh access is truly required in single user mode, I'd say at the very least you'd want to specify that with an *additional* kernel parameter -> "single ssh". I really don't think you'd want to open up every user who thinks he's in single-user mode to ssh access from outside.
