Still, since debian doesn´t have something like %_smp_mflags some setting in
pkgs meta would be the easiest since one then doesn´t have to modify the
original package (if one imports a debian / buntu package).

A correct Debian package will check for the environment variable
DEB_BUILD_OPTIONS and one can disable parallel make by setting it like
this:

DEB_BUILD_OPTIONS=parallel=1

I'm not sure how commonly Debian packages implement this correctly, but even
if some package would fail to do so fixing that is trivial even for somebody
not familiar with the package.


Please add something like this

Just supporting setting environment variables from metadata would solve the
parallel builds issue and might have other useful use cases. Well, OBS is open
source so just asking for more features might not be the fastest approach to
get it done. Unfortunately I have no clue, which parts of the not so small
source to look at. If somebody could give a hint.

I would implement this via a prjconf feature. Something like

ParrallelBuildJobs: 1

Support for such a keyword would be needed to get added to the build script:

git clone git@xxxxxxxxxxxxx:opensuse/build.git

Have also a look at the commit which introduced parrallel build for debian:

cd8192f0e9cf89e76e9f3dca6d6400018f7028f4



and leave parallel builds enabled.
