The instructions are not Linux 101 and assume a basic understanding of Linux or the ability to google and learn.
I did a little investigation and it seems you are pretty active in all that stuff - that too is interesting.
Yes very interesting that the guy on the support team for all the *arrs and who also dabbled in dev work is active on the wiki xD
- The user
radarr
is created
but where and how?
OS dependent and the user should know how to create users if they wish to run as radarr.
- The user
radarr
is part of the group media
OK but in what file/folder?
Folders have nothing to do with a user being part of a group
- Your download clients and media server are part of the group
media
Fine with me. I guess that means, say, sabnzbd+ but so what? All this stuff has to do with file/folder properties and permissions.
So radarr can actually access the files. Otherwise most will have sab run under its own user and group and question when they have issues importing
- You created
/var/lib/radarr
and ensured the user radarr
has read/write permissions
I didn’t because nothing in these installation have told me why or how or even when.
The why is clear on the wiki: for the appdata folder where the config will be stored.
How - again the guide is not Linux 101 and assumes a basic understanding or google ability
When - prior to proceeding with the installation steps
