    initramfs-live-install*: fix the "install" boot option
    
    The install boot option was giving the following error when one tried to
    install the live image on a  permanent storage of a BSP.
    
    cat: write error Invalid argument
    Installation image failed
    sh: can't access tty: job control turned off
    
    Further digging into the issue, found out that the install script was trying
    to do this:
     cat /proc/mounts > /etc/mtab
    
    And in the base-files recipe the /etc/mtab is made soft link to /proc/mounts.
    So the cat command was failing to write on /etc/mtab. As the contents of
    the /proc/mounts is already reflected in the /etc/mtab file due to the
    symlink-ing, there is no need for this step to recreate /etc/mtab in the
    install script. So just removing this unnecessary step, which solves the
    install issue of the live images.
    
    Fixes this bug:
    [YOCTO #4229]
    
    (From OE-Core rev: 2f5d41f94c53aaf606de66891c37de0dbd86f54b)
    

Reverting this will get the mtab file back

FYI, either this commit can be reverted, or the base-files recipe can be updated similar to dylan release.
Comment 3 Ross Burton 2013-05-16 16:43:56 UTC 
I've reverted for now.
