Details

Description:

Running archbuild in parallel on an empty /var/lib/archbuild directory results in a contention. Both processes try to clean and recreate the chroot environment.

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:

(cd abs/core/tzdata; extra-i686-build -- -T)& (cd abs/core/which; extra-i686-build -- -T)
   archbuild.diff (0.7 KiB)
This task depends upon

I can see the rational for the lock, but I'm not sure why you would ever do this.

When i update my arch systems. I build the packages from source. Doing that with parallel-moreutils is a lot faster.

If you set the make jobs correctly, it shouldn't be.

That was first thing i did. Unfortunately it does not help much. It does not affect parts of the build process (download, setup environment, compression). Also a lot of packages do not honour it or only partial. Using parallel speeds up a complete rebuild a lot for me
