System user and group

[stintel]

It is common practice to use different UID/GID ranges for human users and groups vs users and groups used for services. Adding the users and groups as system users and groups ensures this.

Many distros do this as well when a user or group is created by a package. For example, see https://www.debian.org/doc/debian-policy/ch-opersys.html#s9.2

I like this, and was gonna file it myself, but was too lazy to do the PR. Thanks!

3 years ago, I thought it was the rvm user itself (doesn't appear to be one). I didn't fully realize that it was the users I was trying to add to the rvm group. It was my bad for not paying attention, but thank you for having the "$create" parameter to turn it off. I was already managing that user anyhow, just that previously we both had ensure_resource, and they were "close enough" to match before. ;)

It's not that I don't agree with the change, but in my lack of sleep induced madness it saddened me enough to reply.

I am actually sortof re-thinking whether the "railsapp" user should be considered a "system" account or not, but for now I am stuck in shibboleth land, pray for me. :)
