    Good coverage.
    Should that not be “Low Down” rather than “Lay Down” ?
    I feel that the “phantom boot” nature of ureadahead deserves a mention, it is a startup strategy rather than a persistent feature, so it may be out of discussion scope.
    init deserves a nice tree graphic to illustrate.

      no its lay down as it shows how the system is laid down i.e. comprising of init process and all…

      And yes, you are right ureadahead should be there as it reads the files required for boot in advance of their use in the page cache. It starts when the mountall is just about to start and stops after all the old style sysvinit jobs are run..
