From 7136cbc64e5efb09f3fae3e2e35a181ca3d66dd4 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Wed, 13 Nov 2013 18:05:30 +0000 Subject: staging: Use hardlinking for sysroot_stage_dir This saves about 2GB on a core-image-sato build so is worth doing and is consistent with our efforts to try and decrease our build footprint. Build time in my local test seemed unaffected but on more IO bound machines it should help.
