Description Bastien Nocera 2005-10-27 10:41:03 UTC 
+++ This bug was initially created as a clone of Bug #171871 +++

Present in RHEL3 (mkinitrd-3.5.13-6.1) and RHEL4 (mkinitrd-4.2.1.6-1).

1. Run mkinitrd on the attached fstab
2. the linuxrc will contain a 3 line root mount command:
 mount -o defaults
 defaults --ro -t ext3
 ext3 /dev/root /sysroot
instead of:
 mount -o default --ro -t ext3 /dev/root /sysroot

The fix is to replace the following awk commands:
 rootfs=$(awk '{ if ($1 !~ /^[ \t]*#/ && $2 == "/") { print $3; }}' $fstab)
 rootopts=$(awk '{ if ($1 !~ /^[ \t]*#/ && $2 == "/") { print $4; }}' $fstab)
with:
 rootfs=$(awk '{ if ($1 !~ /^[ \t]*#/ && $2 == "/") { print $3; exit }}' $fstab)
 rootopts=$(awk '{ if ($1 !~ /^[ \t]*#/ && $2 == "/") { print $4; exit }}' $fstab)

(Notice the exit after the print statement)
