# Build-time functionality
# ========================
#
# The USE variable is used to enable optional build-time functionality. For
# example, quite a few packages have optional X, gtk or GNOME functionality
# that can only be enabled or disabled at compile-time. Gentoo Linux has a
# very extensive set of USE variables described in our USE variable HOWTO at
# http://www.gentoo.org/doc/use-howto.html
#
# The available list of use flags with descriptions is in your portage tree.
# Use 'less' to view them: --> less /usr/portage/profiles/use.desc <--
#
# Example:
USE="-X -gtk -gnome -dvd -usb -dvdr -xv php wvdial pppconfig samba arch apache fetchmail squid sendmail procmail -alsa bootsplash -qt -kde mmx -3dnow -3dnowex -unicode"
LINGUAS="ru"
# Host Setting
# ============
#
# If you are using a Pentium Pro or greater processor, leave this line as-is;
# otherwise, change to i586, i486 or i386 as appropriate. All modern systems
# (even Athlons) should use "i686-pc-linux-gnu"
#
CHOST="i586-pc-linux-gnu"

# Host and optimization settings
# ==============================
#
# For optimal performance, enable a CFLAGS setting appropriate for your CPU
#
# -mcpu= means optimize code for the particular type of CPU without
# breaking compatibility with other CPUs.
#
# -march= means to take full advantage of the ABI and instructions
# for the particular CPU; this will break compatibility with older CPUs (for
# example, -march=athlon-xp code will not run on a regular Athlon, and
# -march=i686 code will not run on a Pentium Classic.
#
# CPU types supported in gcc-3.2 and higher: athlon-xp, athlon-mp, athlon-4,
# athlon-tbird, athlon, k6, k6-2, k6-3, i386, i486, i586 (Pentium), i686
# (PentiumPro), pentium, pentium-mmx, pentiumpro, pentium2 (Celeron), pentium3,
# and pentium4. Note that Gentoo Linux 1.4 and higher include at least gcc-3.2.
#
# CPU types supported in gcc-2.95*: k6, i386, i486, i586 (Pentium), i686
# (Pentium Pro), pentium, pentiumpro Gentoo Linux 1.2 and below use gcc-2.95*
#
# Decent examples:
#
CFLAGS="-mcpu=pentium3 -O3 -pipe"
#CFLAGS="-O3 -mcpu=i686 -funroll-loops -pipe"

# If you set a CFLAGS above, then this line will set your default C++ flags to
# the same settings. If you don't set CFLAGS above, then comment this line out.
CXXFLAGS="${CFLAGS}"

# Advanced Masking
# ================
#
# Gentoo is using a new masking system to allow for easier stability testing
# on packages. KEYWORDS are used in ebuilds to mask and unmask packages based
# on the platform they are set for. A special form has been added that
# indicates packages and revisions that are expected to work, but have not yet
# been approved for the stable set. '~arch' is a superset of 'arch' which
# includes the unstable, in testing, packages. Users of the 'x86' architecture
# would add '~x86' to ACCEPT_KEYWORDS to enable unstable/testing packages.
# '~ppc', '~sparc', '~sparc64' are the unstable KEYWORDS for their respective
# platforms. DO NOT PUT ANYTHING BUT YOUR SPECIFIC ~ARCHITECTURE IN THE LIST.
# IF YOU ARE UNSURE OF YOUR ARCH, OR THE IMPLICATIONS, DO NOT MODIFY THIS.
#
ACCEPT_KEYWORDS="x86"

# Portage Directories
# ===================
#
# Each of these settings controls an aspect of portage's storage and file
# system usage. If you change any of these, be sure it is available when
# you try to use portage. *** DO NOT INCLUDE A TRAILING "/" ***
#
# PORTAGE_TMPDIR is the location portage will use for compilations and
# temporary storage of data. This can get VERY large depending upon
# the application being installed.
#PORTAGE_TMPDIR=/var/tmp
#
# PORTDIR is the location of the portage tree. This is the repository
# for all profile information as well as all ebuilds. This directory
# itself can reach 200M. WE DO NOT RECOMMEND that you change this.
#PORTDIR=/usr/portage
#
# DISTDIR is where all of the source code tarballs will be placed for
# emerges. The source code is maintained here unless you delete
# it. The entire repository of tarballs for gentoo is 9G. This is
# considerably more than any user will ever download. 2-3G is
# a large DISTDIR.
#DISTDIR=${PORTDIR}/distfiles
#
GENTOO_MIRRORS="ftp://ibiblio.org/pub/Linux/distributions/gentoo distfiles.gentoo.org"
# PKGDIR is the location of binary packages that you can have created
# with '--buildpkg' or '-b' while emerging a package. This can get
# upto several hundred megs, or even a few gigs.
#PKGDIR=${PORTDIR}/packages
#
# PORTDIR_OVERLAY is a directory where local ebuilds may be stored without
# concern that they will be deleted by rsync updates. Default is not
# defined.
#PORTDIR_OVERLAY=/usr/local/portage

# Fetching files
# ==============
#
# If you need to set a proxy for wget or lukemftp, add the appropriate "export
# ftp_proxy=
" and "export http_proxy=
" lines to /etc/profile if
# all users on your system should use them.
#
# Portage uses wget by default. Here are some settings for some alternate
# downloaders -- note that you need to merge these programs first before they
# will be available.
#
# Lukemftp (BSD ftp):
#FETCHCOMMAND="/usr/bin/lukemftp -s -a -o \${DISTDIR}/\${FILE} \${URI}"
#RESUMECOMMAND="/usr/bin/lukemftp -s -a -R -o \${DISTDIR}/\${FILE} \${URI}"
#
# Prozilla (turbo downloader)
#FETCHCOMMAND='/usr/bin/proz --no-getch -s ${URI} -P ${DISTDIR}'

# Advanced Features
# =================
#
# MAKEOPTS provides extra options that may be passed to 'make' when a
# program is compiled. Presently the only use is for specifying
# the number of parallel makes (-j) to perform. The suggested number
# for parallel makes is CPUs+1.
#MAKEOPTS="-j2"
#
# AUTOCLEAN enables portage to automatically clean out older or overlapping
# packages from the system after every successful merge. This is the
# same as running 'emerge -c' after every merge. Set with: "yes" or "no".
#AUTOCLEAN="yes"
#
# FEATURES are settings that affect the functionality of portage. Most of
# these settings are for developer use, but some are available to non-
# developers as well. 'buildpkg' is an always-on setting for the emerge
# flag of the same name. It causes binary packages to be created of all
# packages that are merged.
#FEATURES="sandbox ccache buildpkg"
#
# RSYNC_RETRIES sets the number of times portage will attempt to retrieve
# a current portage tree before it exits with an error. This allows
# for a more successful retrieval without user intervention most times.
#RSYNC_RETRIES="3"

На счет когда ставилась, понятия не имею. Но файлы в системе и за 2005 год есть.
По второй части вопроса...Отвечу вопросом...Какой коммандой можно это сделать?

Понимаю что не культурно но все же.

крамольная мысль .....

если человек не имеет опыта, а эксперементировать на сервере - не есть хорошо...

ядро 2.6.12 - это где-то 2006 год и обновление отнюдь не тривиальная задачка для новичка....

если на локальной машинке развернуть stage3 и удалить всё лишнее типа /dev /etc/ssh /etc/passwd ну и т.п. что может уронить систему при наложении

завернуть снова в stage3, на сервере скопировать /etc в сторонку и развернуть stage3

какие проблемы могут быть?

главное не затронуть критичные рабочие процессы и обеспечить доступ по ssh

думаю что для новичка при правильной комплектации stage3 (stage4) это путь минимизировать риск уронить сервер насмерть

понимаю, что мысль крамольная, но.... ????
