Minor warning: if you are using backuppc to back up a host with rsync over ssh, it will fail if there is any output before the rsync startup. Native rsync will ignore it, but not the backuppc server's rsync-in-perl implementation. So, randomly adding messages at login may have side effects.
does it fail, with enough context to figure out what happened ? if so, we then just need to make it easy to turn off.
I think it tries to interpret the ascii value of the text as an rsync version number and logs it as a mismatch. So not exactly a 'user friendly' error message, and since backuppc normally runs unattended you may not find out about it until several days have passed - and then only if your email setup works.
But,if it only displays on interactive logins (where ssh doesn't pass a command) it should be OK.
