    1 #!/bin/bash
    2 #
    3 # filelist - prepare a list of the files in a built system.
    4 # This is for use in comparing two builds, to answer the
    5 # question "can it build itself" ?  Obviously, it can also be
    6 # used to compare two partial builds to see what changed.
    7 #
    8 # Call this script with the path to the root of the system.
    9 # If you are running the new system, the path is probably '/'.
    10 # Alternatively, the system might be mounted at /mnt/lfs, or
    11 # it might have been copied to ~/build1 or wherever.
    12 #
    13 # The output is a single file, filelist-CCYYMMDDhhmm
    14 # e.g. filelist-200510052108
    15 # which contains a list of the files to compare.
    16 # It excludes certain files which are not of interest (/tools,
    17 # /cross-tools, /home) together with any mounted filesystems.
    18 #
    19 # you should run this as a regular user - this will cause files
    20 # in e.g. /root to be ignored.
    21 #
    22 # I like to build a graphical desktop before using a new system
    23 # to see if it can build itself.  Filelist supports this by allowing
    24 # you to list the files at any time.  My normal process is:
    25 #
    26 # 1. Build an LFS system as normal.
    27 # 2. Build some extras before booting (nfs client, ntp, openssh,
    28 #    lynx, dhcp client, etc).
    29 # 3. Boot the new (first) system, set up users, run filelist.
    30 # 4. Build X and whatever else I want to use.
    31 # 5. Build the second system.
    32 # 6. Build the same extras for the second system.
    33 # 7. Boot the second system, to prove it works.
    34 # 8. Reboot to the first system, mount the second system at /mnt/lfs,
    35 #    then run filelist on /mnt/lfs and run the comparison.
