[SOLVED] Why is the package cache cleaned in a post-transaction hook?

Hi, I noticed that pacman stopped storing packages in `/var/cache/pacman/pkg/`. I found out it's because there is a post-transaction hook "Cleaning up package cache..." (see pacman output below). The hook definition is in `/usr/share/libalpm/hooks/package-cleanup.hook`. I have no idea how this file got there. I tried `pkgfile` to find which package this belongs to, but no luck. I did notice that arch docker has such a file:

https://github.com/archlinux/archlinux- … eanup.hook

I did tinker around with docker, and now I'm worried that this somehow leaked into the host system (I don't know if that's possible?). Anyways, I don't like that hook. I know I can just delete the file, but the question remains how it got there, and how I can make sure it doesn't get there again??

Thanks for your help!

This is what pacman -Qo is for.

Re: [SOLVED] Why is the package cache cleaned in a post-transaction hook?

Thanks for the hint, it says that no package owns it.

I probably made a mistake when I played with the archlinux-docker repository and somehow copied that file over. I'll mark it as solved.

Sorry for taking your time, and thanks for the reply!
