The motivation for this was to see if it's
possible to go from disk partition to completed Gnome build in less than
a day. I don't mean 24hrs, I mean to start around 7 am and finish
around 10 pm.I wrote a script that
builds scripts to install packages in each section of the book -
security, libraries etc. I started with an LFS script from Firerat and
developed things from there.
I used all the packages that are either required or recommended dependencies,
plus a few extras- basically everything that's essential for a Gnome build.
I run each section script and when a packages dependencies (required plus
recommended) are satisfied, the package is installed.What
follows is the time that I started various scripts for LFS and then
BLFS, the interval time for key parts of the build and any worthwhile
comments, for e.g. any problems encountered. I hope this table formatting
is maintained, otherwise you won't be able to read a thing.

As you can see, it took almost exactly 13hrs to install BLFS.
So I didn't make the 10 pm target. May be I could change the order in which I
run the scripts.Obviously
this is an optimization problem but not one with an analytical
solution. Empiricism rules here. Installing everything as a package
user also slows things a bit because there's lots of group and
permission changes going on and also writing all the output for each
package to configure, make and install logs doesn't help the speed.
I also had a couple of delays caused by my errors. I forgot the sed for
udev-extras. It won't install from the book and I wasted time doing it
manually. I also renamed the webkitgtk patch to webkit but forgot to
name it back to webkitgtk so the book commands would work and I forgot I
had to reinstall gobject-intro in order for librsvg to compile.
However, this time loss wasn't enough to get me to the 10 pm target.The real
killers are llvm, qt4, webkitgtk, evolution and firefox - and may be a few
others I've forgotten about.
So
there's the challenge for you - can you install LFS and a Gnome desktop
starting at 7 am and finishing at 10 pm? May be if you've got a quad
core machine, a faster web connection, you install as root and your scripts
work more efficiently
than mine ( and you don't make any mistakes). Quite a tough challenge though.
jb.
p.s.
I've still got the BLFS log with the order and all the install times
if anyone's interested. There are a total of 429 packages installed, I
think. That includes LFS.
