As much as I’d love to see SLP integrated with Distcc I’ve come to the realisation that Gentoo isn’t the place for the patch to be implmented and tested. Rather, it should be applied to the source tree UPSTREAM for the entire user base to test, likewise with all other patch enhancements.
Obiously it’s different if the package has no maintainer and hasn’t seen the loving hand of a programmer in years or if the patch is to fix a serious Gentoo-specific bug, like the TMPDIR issues in distcc from a year or two ago.
