Which locations need to be writable?

[groggily]

/raven is definitely needed to be writable. But what about other locations?

[kraileth]

The package manager needs to be able to write to /var/db/rvn/ (for the package database) as well as /var/cache/rvn/ for the directory where the downloaded package files are cached.

[jrmarino]

and that's just rvn. ravenadm has several directories it writes to as well (if you want to build packges).

[jrmarino]

rvn -vv

might show some directories we may have forgotten about as well

[groggily]

Here is the output of rvn -vv on my system:

this isn't really linux-specific, putting it in Q&A
