How to fix system-wide permissions? [SOLVED]

Hello,

Due to a failed hard drive, I had to restore a system from backup, but for some reason the permissions weren't preserved in my backup drive (uid=1000,gid=1000 for all files in the filesystem).  How can I rebuild the file permissions using the mtree? 

I've tried the AUR package pacman-fix-permissions, but it fails with the error "can't open or download 'acl' package".

edit: there also used to be a shell script on xgit but the url is dead

this happened to me once too, from memory i just re-installed ALL packages on my system which reset the permissions, this had to be done with arch-chroot from a working installation. i cant remember how usable the system was after but its worth a try anyway.

Re: How to fix system-wide permissions? [SOLVED]

Reinstalling the packages didn't work.  The issue is primarily with the config files, although it does set the correct permissions on everything in /usr; as a note, I was able to reinstall everything without a chroot, but had to go in the order of installing utils-linux and some other base packages before installing the rest. 

If I run `pacman -Qkk`, it still shows thousands of permissions issues but doesn't tell me what the expected permissions are.  If it at least told me the expected permissions, then I could pipe it into a python script similar to pacman-fix-permissions and just have it automatically fix everything. 

Is there an option to have pacman print the expected permissions on these mismatched files?

EDIT:

`paccheck --file-properties --quiet | grep permission` ; I should be able to write a bash script for that easily.
