[Nix-dev] Polkit action files installed via nix-env don't appear to be recognised by Polkit/Pkexec/Pkaction

[Roger Qiu]

Hi all,

Normally a polkit action file on a non-NixOS system would be installed 
in /usr/share/polkit-1/actions. On NixOS this location is instead at 
/run/current-system/sw/share/polkit-1/actions. The action files stored 
here are recognised by polkit, which can be demonstrated by running 
`pkaction`, this results in showing the titles of each action id.

However some packages may supply action files, and are installed via 
nix-env. The action files in this case are instead stored in 
~/.nix-profile/share/polkit-1/actions. My tests show that these action 
files are not being recognised by polkit. Running pkaction does not show 
any package the action files that are inside ~/.nix-profile/...

Is there a work around here?

Browsing the polkit docs doesn't mention anything about looking up 
user-specific action files, they all just say action files are to be at 
/usr/share/polkit-1/actions. If polkit only looks up 1 location, then 
should nix-env be symlinking action files into 
/run/current/system/sw/share/polkit-1/actions?

Thanks,
Roger
