Description nusenu 2016-01-25 19:38:17 UTC

Description of problem:
I'm currently implementing per-instance tor-user support for Fedora/EPEL where every tor instance is run with a distinct system user (Debian comes with that out of the box).

Filesystem permissions and systemd hardening make it a bit hard on RPM based systems.
 
Default permissions:
drwxr-x---. 2 toranon root 4096 Jan 25 00:00 /var/lib/tor

The change that is required is minimal, adding the following like to the service file would do it: 

ReadWriteDirectories=/var/lib/tor-instances
(this is also the default per-instance datadir location on Debian)

Optionally also:
ReadWriteDirectories=/var/log/tor-instances


Note: I don't want every tor-instance account become a toranon group member because that would allow them to do more than they should.

/var/lib/tor-instances does not need to be created by the package.
I'll create it as needed with root:root 0755 permissions.

thanks!

It doesn't make sense to add ReadWriteDirectories for a directory that isn't part of the Tor package.

You can extend the Fedora service file using systemd snippets:
