annotate include.sh @ 253:f93932523a08
Reorder forkbomb build so ./host-tools.sh gets built first. Then toybox
utilities can be used to extract all the other packages (patch, bunzip,
sha1sum, echo, eventually tar...) Motivated by a bug I encountered in gnu
patch on Kubuntu 7.10 that's insisting linux-2.6.13-cmdline.patch is
a reversed patch, when it isn't. (That patch has been happily applying for
over a year now, and I examined it by hand. The bug's in the Ubuntu patch
command. Not my problem.)
