Thank you.
Well I was blamed out of blfs-dev as they stated automated processing is an 
item of dump users who like brainless installation.
My position is quite contrary, as I believe, that automated processing is the 
base for certain quality.
I'm not that good in copy by keyboard and quite errorneous.
So with LFS I put the commands together in few Makefiles and startet the build 
after chapter 5 (with a clean fs) until the build succeeded with 2 or 3 

With BLFS I wanted to have the same security, but with that lot of packages I 
negated big keyboard copy-sessions.
The tools I found worked with blfs 1.0 - and the book changed that lot, that 
the tools I tested didn't work with the current release.
Additionally I wanted to learn perl, as I often need to do quick text 
So I wrote a script to build a Makefile based on my package selection.

Then I builded a server upon LFS with the scripts. Naturally I had several 
bugs in the script, but when I was done with the server, the script matured 
that much, that I could also use it for quality-investigation of the book.

Well, as I'm quite a perl-newbee, the script is not at all "high 
sofisticated", but it works. And is it is build with modules, it's easy to 

As I found no interest in blfs-dev supporting (or even admitting) automatic 
processing, I took a closer look at ALFS.

Well, my opinion is, having a book like LFS or BLFS as knowledgebase, it is 
poor practice to need additional information sources.
I very like the way to teach linux, but I don't like to have to copy the 
build-instructions by keyboard.

So what do you think about patches to the blfs-book to correct the 
dependencies or other details needed for automatic processing?
Those patches could be saved in the ALFS-repository ...

Well, I did not either. But as I got so much out of LFS and BLFS, I wanted to 
give a bit back to the teams and for so I spend time to edit the book and
expand my script.
As it already is able to handle dependency walking and generates 
build-commands, it's only adding another module to add profile generation.

I really don't want anybody throw away anything! -

I downloaded the profiles from LFS 5xx and I worked with the dtd and 
crosschecking the profiles.

Most differences are IMHO cosmetic i.e. some packages change the working 
directory during the build commands, so it's not enuf having the base in 
stageinfo - so I added the base to every command. 
Hope the command is able to check, whether it needs the base information or 

How is the handling of environment vars just for a single command?
I did not find a profile for alsa-driver yet, theres a CC=... just before 
the ./configure and I remember other builds, where CFLAGS where set after ./
configure, but before executing make.
What is the right way to do this with ALFS?

Kind regards
