# Script for setting up "Prefix Gentoo"
# Author: rabbe@gentoo.se
#
# This script was derived from the "Gentoo Prefix Portage Bootstrap
# Process for Solaris" webpage at
# <http://www.gentoo.org/proj/en/gentoo-alt/prefix/bootstrap-solaris.xml>.
# Successful bootstrapping has been verified for Solaris/x86 and
# Solaris/sparc. More work is needed on Linux/x86.
#
# Changes have been made by trial-and-error to make the script run
# all the way unattended. Root privileges are not required. It is
# likely that the script to some extent reflects the particular set
# of bootstrapping tools (GCC compiler etc) being used.
#
# Numbers N.nn refer to the Code Listing numbers of the webpage. Extra
# steps have been introduced where needed.
#
# The script is sectioned into "levels", each level corresponding to
# a Code Listing in the webpage. Whenever a new level has been reached
# a timestamp is placed in the $EPREFIX/bootstrap/progress directory.
#
# It is the intention that the script should die as soon as something
# goes wrong, with an indication of the troublesome level. After fixing
# the problem the script can be restarted and will then skip over levels
# that have already been reached. By removing selected timestamps the
# script will re-run the corresponding bootstrap steps.
# 
# The script finishes in less than 10 hours on a Solaris x86 system
# (hardware details unknown). The final size of $EPREFIX is of the
# order 0.8 GB.
#
# FILES CREATED BY THIS SCRIPT
#
# Lots of files under $EPREFIX
# Certain config files under $HOME/.subversion/
#
# BOOTSTRAPPING TOOLS REQUIRED
# 
# Quite a few software components are required for a successful
# bootstrap installation. Here is an attempt at a list (likely to
# be incomplete):
# 
# gcc + ar + ld
# gmake or make
# grep + egrep + fgrep + or ggrep + gegrep + gfgrep
# ginstall or install
#
# TODO
#
# - Is it really necessary to have `hash -r' in some places?
# - Investigate FIXMEs.
