    Since I've run with profile they have gone ??
    Where these the cache files ??
    How do I recreate them ??

    Thanks
    You should put "profile" only once (that generates those two files) while booting with pressing E (for edit) while on the boot (grub) menu and then selecting the line where kernel You want to boot is and adding "profile" to the and of that line, press Enter and then B (for boot) and that is it. remove "profile" from menu.lst. the way You have done it now You are profiling at every boot which is wrong ...

    Thanks for the reply zika

    I have removed profile from my menu.lst, but boot & desktop have not been recreated in /etc/readahead/

    Do I need to manually create the files for 'profile' to update ??

    Thanks

    when You reboot machine, on grub menu navigate to kernel You want to use, click on E, navigate to line which lists that kernel, click on E, go to the end of the line, add "profile" (with space in front of it), click on Enter, then click on B, let it do its magic and enjoy ...

    I keep seeing people noting that they can't find .readahead, which is a hidden directory ("View > Show Hidden Files" to discover). Could this be a similar issue in /etc/ ? (I don't use it myself so I really can't speak to the issue.)

    or a simple
    Code:
    ls -lag /etc/readahead
    in Terminal window.

    `ls -lag'? You know the `-g' overrules the `-l' right?
