My aim is to have the ability to regularly build and maintain
completely customized Linux systems. I simply don't want to be
dependent - at any stage - on the whims or habits of a distribution.
While LFS allows me to build a completely customized Linux system, it
takes, as you say, a lot of time and effort to build a single one.
Also, it offers nothing in the sense of package-management.
So, what I'm looking for is something to automate the LFS
build-process and to do it under some system of package-management.
Portage seemls likely to meet those needs.

>From what I read about stage1 and stage2, they both come as is, which
is somewhat problematic for my needs (for examle, if I want to use one
version of gcc instead of another). Even if stage1 is used 'out of the
box', some mechanism should be in place in order to build a new system
on a chroot environment, no?

The ROOT variable is probably a major part of the solution, but is it
enough? I've also found '/usr/portage/scripts/bootstrap.sh', which
seems suspiciously relevant, but comes with little external
documentation.

I'm sorry that you find my request rude. I would rather not go through
200 messages every day if I could help it, and I personally don't find
it too troublesome to add an address to the CC line. Replying to the
list and having me as CC will obviously not prevent others to take
place in the discussion or read it later on as reference.
At any case, I would look in online archives to search for any
messages which haven't reached me.

Hi,

I'm considering using Portage to build a Linux From Scratch system
(LFS basically means building a completely customized Linux machine,
using a toolchain).
The little documentation online regarding such a feat, along with my
little experience with Portage, means that I would have to go
knee-deep (in creating ebuilds) before even knowing if it is feasible,
so I thought I'd ask here for some insight.

I noticed that the Catalyst project deals with toolchain building, but
it is Gentoo-centric, and with virtually no documentation.
I also noticed that Portage allows defining the ROOT environment
variable (in '/etc/make.conf') in order "to  specify  the  target
root  filesystem to be used for merging packages or ebuilds". I wonder
if emerging this way is enough to build a runnable OS, or if there are
special prerequisites the host system (aside from running emerge) or
destination file-system must meet.

Thanks in advance,
  Alon
