| |
-stable review patch. If anyone has any objections, please let us know. ------------------
From: Nix <nix@esperi.org.uk>
When I built 2.6.17 for the first time I was a little surprised to see my kernel putting on >500Kb in weight.
It didn't take long to work out that this was because my initramfs's contents were being included twice in the cpio image.
A make V=1 makes the problem obvious:
/bin/sh /usr/packages/linux/versions/i686-loki/scripts/gen_initramfs_list.sh -l "usr/initramfs" > usr/.initramfs_data.cpio.gz.d /bin/sh /usr/packages/linux/versions/i686-loki/scripts/gen_initramfs_list.sh -o usr/initramfs_data.cpio.gz -u 0 -g 0 "usr/initramfs" "usr/initramfs"
Note that doubling-up of the "usr/initramfs", which leads to gen_initramfs_list.sh dumping the thing into the cpio archive twice.
The cause is an obvious pasto, fixed thusly:
