Let's use 15 GiB. We used to run out of space periodically because our RPM build jobs were creating RPMs in $HOME/rpmbuild which jenkins never purged. I reconfigured Jenkins to use the GIT workspace as the RPM build dir, so jenkins always purges RPMs. Since then we've not run out of space again AFAIK. None the less, I agree that 15 GiB is probably the min we need

I'd give it 300 MB swap max.
