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.
