npm wants to install to /home/mediagoblin, but the mg system account doesn't use a home dir

Description

We specifically don't create a home directory for the 'mediagoblin' system account as part of the setup process, but npm wants to install to the mediagoblin user home dir:

Is there an alternate install location for this part of the process (e.g., somewhere in /srv/mediagoblin.example.org/bin ) or should we create a mediagoblin home directory?

I'm setting this as a 0.8 milestone bug because I think we need to decide which approach to take & document things appropriately in the deployment docs.

I suggest we specifically create a MediaGoblin user home directory in the installation instructions. When I install GMG, I specify /srv/mediagoblin as home directory, as below.

# useradd -c "Gnu MediaGoblin user account" -d /srv/mediagoblin -g mediagoblin -m -r mediagoblin

Another option would be to use /var/lib/mediagoblin as a home directory, which is suggested as the working directory in more recent releases. I don't think we should use /home/mediagoblin.

Thanks for the input, ayleph! In terms of the two suggestions, I don't see a clear winner between the two options after reading about both options in the filesystem hierarchy standard documentation.

Anyone else have a preference on this?

As a note, setting things up with /srv/mediagoblin as the home directory "worked for me" on our mediagoblin.chicagolug.org instance.

I'm okay with recommending this option in the deployment docs if I can get another +1 on it.

I should add a comment that using /srv/mediagoblin as the mediagoblin user home directory makes sense the way I deploy my instance, where I have a generic /srv/mediagoblin directory and then place my actual installations in a subdirectory, like so.

/srv/mediagoblin
/srv/mediagoblin/mediagoblin -> /srv/mediagoblin/mediagoblin-0.8.0
/srv/mediagoblin/mediagoblin-0.7.2
/srv/mediagoblin/mediagoblin-0.8.0

If someone instead installs to /srv/mediagoblin.example.org then it follows that instead of setting the home directory to /srv/mediagoblin, they should instead set the home directory to /srv/mediagoblin.example.org.

Maybe it makes more sense to use /var/lib/mediagoblin as the home directory, so we don't have to guess where the user plans to install their instance.

Thanks for the input, ayleph and others. In discussing with Chris on IRC, we're going with a home directory for the MG account.

sudo useradd -c "GNU MediaGoblin system account" -d /home/mediagoblin -U -m -r mediagoblin

I've tested that command as working on Debian Jessie and Fedora. I haven't made the commit yet, but will do so shortly.

Fixed with commit 44db13fa840e23c30d03709815d38b9c44d4df18. Thanks!

I still don't see any reason to create /home/mediagoblin for a system account. It's not standard practice. You don't see /home/postgres, /home/apache, /home/mediawiki, etc.

Unless the user intends to actually clone mediagoblin into /home/mediagoblin, it's going to be empty except for a few dot-directories like /home/mediagoblin/.python-eggs, /home/mediagoblin/.npm, etc.
