Description Matt Turner gentoo-dev

2010-12-24 01:25:30 UTC

Attached is a patch which replaces tar -j with tar -I pbzip2 in order to make use of parallel bzip2.

pbzip2 is a very small program, so it's not a problem to depend on it. This enhancement is wanted because multicore systems are extremely common and we have a very simple way to speed-up part of the stage building process.

It'd also greatly help multicore, but otherwise slower systems, like the ARM Pandaboard or the Sibyte MIPS system I'm using.

Please commit.

(We can also use the parallel gzip implementation, pigz, but since bzip2 is used so much more often in catalyst, I thought this should be the first step.)

Forget it. lbzip2 with USE="symlink" works.
