From 13259459e200a237ca486cbe1123a0b0a4d1eebf Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 8 Nov 2013 15:18:00 +0000 Subject: kernel: Use hardlinks for do_populate_sysroot for speed The kernel tree is large and doesn't need to be copied. Override the default sysroot handling function to use a hardlink copying function in python. This commit also drops the copying of the /lib directory which just contains the kernel modules. We never use those in the sysroot so there is little point in carrying those around. For linux-yocto this takes the do_populate_sysroot time 24s -> 14s.
