           Summary: checkroot.sh and /proc/mounts issue
           Product: Openembedded
           Version: unspecified
          Platform: ARM
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Build
        AssignedTo: openembedded-devel at lists.openembedded.org
        ReportedBy: shanevolpe at gmail.com

checkroot.sh right before it is finished checks the privs. of rootfs in
/proc/modules.  If the rootfs is rw then checkroot.sh exits otherwise it
remounts it as rw.
When my system enters this script this is what /proc/mounts looks like:
    rootfs / rootfs rw 0 0
    /dev/root / jffs2 ro 0 0 
    proc /proc proc rw 0 0
checkroot.sh does its check and sees rootfs is rw so it exists with out
mounting  "/" as rw.  However /dev/root is the real "/" and it is mounted as ro
so it does need to be remounted as rw or the system comes up with the root file
system in ro mode.

I modified checkroot.sh as follows:
Line: 153
--       if [ $(grep rootfs /proc/mounts | awk '{print $4}') = rw ]; then
++       if [ $(grep "/dev/root" /proc/mounts | awk '{print $4}') = rw ]; then
         exit 0
       fi
       echo "Remounting root file system..."
       mount -n -o remount,$rootmode /

I do not believe this is the best long term solution but it is a temporary one
for me that works. I would like to hear other people's options on this matter. 

Why are there two entries in the /proc/mounts for "/"?  
I verified they are present the minute sysinit calls the first run level
script.

Regards,
Shane
