Yep. Fortunately, thats a cpio file. So uncompress, go to tmp make a
work dir and "cpio -idmvc -I <your uncompressed file name>". Then cd
into the dir and find . -name init. Edit that file. There's two
"ingnorelockingfailure" imperatives in there. One of them names the
volgroup. Add yours to the list (comma, IIRC - use the man page if there
is one).

Then cpio it back up by using the -c param and compress it.
