Comment 15 for bug 857651

My use case is a separate account used to develop or to build packages. This provides environmental isolation from the everyday user account and some security - the separate account might have additional system privileges or private keys. For example:

 Mock -
 kde development - using (now outdated, i think) advice such as at
 A test account for a very old version of amarok with X forwarding

Accounts that can only be accessed by ssh or that don't make sense to log in directly (and are just noise for other users on the machine) but that are otherwise still normal user accounts with home directories and that don't really belong in the system account pid range.

Arguably some of this is better handled by virtual machines nowadays; but the separate build user case for mock is, I believe, still strong. And the ssh keys in a separate account case is reasonable, isn't it?
