The geninitrdsz.c program was originally provided by IBM. An old bug number is referenced in the source. Apparently this program is not generating a useful file any more, so IBM has reworked it and it now generates a load address patch file that can be used when booting an LPAR directly. --- utils/geninitrdsz.c | 51 +++++++++++++++++++++++++++++++++++---------------- 1 files changed, 35 insertions(+), 16 deletions(-) diff --git a/utils/geninitrdsz.c b/utils/geninitrdsz.c index 6dfd976..b8c824a 100644 --- a/utils/geninitrdsz.c +++ b/utils/geninitrdsz.c @@ -1,11 +1,12 @@ /* - * geninitrdsz.c - * Generate initrd.size file for zSeries platforms. + * gen-initrd-addr.c + * Generate initrd.addr file for s390x platforms. * Takes an integer argument and writes out the binary representation of - * that value to the initrd.size file. + * that value to the initrd.addr file. * https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=197773 + * https://bugzilla.redhat.com/show_bug.cgi?id=546422 * - * Copyright (C) 2007 Red Hat, Inc.
