#!/tools/bin/bash -x

## This is based on the first part of the LFS manual, in regards to
## the files that would reside in /tools. The three exceptions are 
## wget, Python, and Perl is compiled fully.

## Also, currently the script does not deal with
## determing if there exist /etc/resolv.conf, so I leave that
## up to you.

## The initial meat for this was found at 
## http://dev.gentoo.org/~vapier/bootstrap-portage, but
## has been heavily modified due to doing "UNINTENDED THINGS"
## That and the developer making that script intended it
## to be installed on an already functioning system not
## shifted to /tools, and well, yah.

## NOTE ON PATHS: It's assumed /bin:/usr/bin:/sbin ... /tools/bin are
## already set for the PATH variable.

# Version of Portage
PV=2.1.2

# CFLAGS, CHOST, ACCEPT_KEYWORDS, ARCH
# NOTE: These are where you can change the processor
# architecture you want to build for. There's also the 
# make.profile that needs to be set later on, based on 
# ACCEPT_KEYWORDS. (ACCEPT_KEYWORDS functions based on 
# architecture. For example, an x86 install would just be x86, 
# PowerPC would be ppc, et cetera.

# They're hardcoded right now, but you get the idea
ACCEPT_KEYWORDS="x86"
ARCH="x86"
CFLAGS="-march=i686 -O2 -pipe"
CHOST="i386-pc-linux-gnu"

# We need an initial directory structure to make things easier on us
# Feel free to clean this up. This has been hand-added as portage borks
# on me wanting a directory NOTE: This is assuming /etc exists, as 
# noted above

# NOTE: There exist the sys-apps/baselayout ebuild. Perhaps this would
# be a nice thing to parse initially. Until then, ugly hack!

mkdir /bin
mkdir -p /usr/bin
mkdir /usr/sbin
mkdir -p /var/log
mkdir /var/tmp
mkdir /tmp

# We also need an ugly hack right now, in order to utilize hard-coded
# paths by the Gentoo scripts. Luckily, by using symlinks with /tools
# prefix, it makes it easy to go in later and remove everything
# portage didn't install, and it's only the /bin directory
ln -s /tools/bin/* /bin/
ln -s /tools/bin/* /usr/bin/
# Why both? It wants python in /usr/bin. Let's just be safe in case
# it wants others

### ****WARNING******
### The following is because I used a different script to bootstrap Python,
### not the LFS way (bootstrap-prefix.sh from the Prefix-Portage files)
### So take this out if you built it with LFS
ln -s /bootstrap/usr/bin/python /usr/bin/

# Now on to bootstrapping portage. Much hardcoded stuff, 
# but I was on intent on just getting it "to work"

# It would also be nice to implement a way to grab the portage ebuild
# file and just parse that, to ensure we're not missing any new additions
# But this is what I have now.
