When I check the permissions with getfacl, the permissions are 750. I tend to leave the permissions like that, I just want to know if this is correct for clarification.
A package maintainer thinks that 755 is correct, though several packages may say that they “own” /usr/share/polkit-1/rules.d.
You can check which one was updated recently and see if you agree with the change:
$ pacman -Qo /usr/share/polkit-1/rules.d
...
/usr/share/polkit-1/rules.d/ is owned by blueman 2.1.4-1
/usr/share/polkit-1/rules.d/ is owned by bolt 0.9.1-1
...
/usr/share/polkit-1/rules.d/ is owned by polkit 0.118-1
/usr/share/polkit-1/rules.d/ is owned by systemd 247.3-1
...
pacman -Qo /usr/share/polkit-1/rules.d shows (e.g.) : /usr/share/polkit-1/rules.d/ is included in linux-wifi-hotspot 4.0.3-1.
A quick search in arch-packages, aur-packages, github and the rest of the internet didn’t gave a reason to change the rights.
I hope I’ll remember when I have to do some changes.
