hi, is there a lightweight gentoo distribution, optimized for a installation under your $HOME directory? it shouldn't consume a lot of space. it should behave like a --prefixe=$HOME installation.


greets,

Sounds like user-mode linux to me. Not with a current gentoo setup available. At least not to my knowledge. :cry:

no, UML is very different. I meant a gentoo installation on any $HOME, not a system in a system.

Indeed. As I said, since there is usually a quota on many administered $HOMEs, it should be bare and slim. I simply want some basic applications in my home which are easy to compile with ./config --prefix=$HOME && make && make install. Yet, some applications have big and cumbersome tail of dependencies. I don't want to spend days of trying the right library combinations, a simple emerge <package> should be able to install the <package> in my $HOME. Does such a gentoo branch exist?

it is normaly possible to do that because the macOS architecture is a prefixed portage

mabe look at the macos installatoin guide

This doesn't seem very practical, but technically, you could compile and program in your home directory after setting up needed missing libraries and proper path variable as needed.

I think something like klik is probably what you need. Since you said you only had a handful of small apps, the static nature of klik images shouldn't be a problem.

I don't know what DE the university uses, or if klik works with Gnome/other DEs, but is that what you are looking for?
(I don't think you can ever expect being about to use portage to emerge into a user's directory.)

You could try using these options:
Code:
man 1 emerge

Quote:
ENVIRONMENT OPTIONS
ROOT = [path]
Use ROOT to specify the target root filesystem to be used for merging packages or ebuilds.
Defaults to /.

PORTAGE_CONFIGROOT = [path]
Use PORTAGE_CONFIGROOT to specify the location for various portage configuration files (see FILES for a detailed list).
Defaults to /.


So, having these while emerging would read the files
Quote:
FILES
/var/lib/portage/world
Contains a list of all user-specified packages. You can safely edit this file, adding packages that you want to be considered
in world set updates and removing those that you do not want to be considered.

/etc/make.conf
Contains variables for the build process, overriding those in make.globals. You should edit this file instead of the ones
listed below.

/etc/dispatch-conf.conf
Contains settings to handle automatic updates/backups of configuration files.

/etc/make.profile/make.defaults
Contains profile-specific variables for the build process. Do not edit this file.

/etc/make.profile/use.defaults
Contains a list of packages which, if installed, cause the respective USE flag to be enabled by default. Do not edit this file.

/usr/portage/profiles/use.desc
Contains the master list of USE flags with descriptions of their functions. Do not edit this file.

/etc/make.profile/virtuals
Contains a list of default packages used to resolve virtual dependencies. Do not edit this file.

/etc/make.profile/packages
Contains a list of packages used for the base system. The system and world sets consult this file. Do not edit this file.

/etc/make.globals
Contains the default variables for the build process. Do not edit this file.

from your PORTAGE_CONFIGROOT dir and would install to ROOT dir.
Take $FAKEROOT as your new root in your home, say gentoo.
I have played with the ROOT env option sometimes and it creates at the new ROOT dir the /var/db/pkg/ dir structure after installing the files. It also considers it when calculating dependencies.
You have 2 options, if your root system is a gentoo system and you are in the portage group, you can emerge --pretend the packages you want to install in your home and then install them with the new env settings using
Code:
ebuild $HOME/$FAKEROOT/usr/portage/xxx-yyy/kkk/kkk-0.0.0.ebuild merge

or if your root is not a gentoo system you have another 2 options:
check for the dependencies yourself and ebuild as above by the order necessary and considering you have done all dependency checkings for every package to ebuild or ebuild an empty system. This, of course, would emerge everything (glibc, gcc, etc...) but could be done using the emerge command instead of manual ebuild commands.

Keeping it minimal, I have just tried the first option and it worked. I have tried it mounting /usr/portage , /etc and /var/lib/portage from the root filesystem in my $HOME/$FAKEROOT/* .
I have installed eix using
Code:
ROOT="$HOME/$FAKEROOT" PORTAGE_CONFIGROOT="$HOME/$FAKEROOT" ebuild $HOME/FAKEROOT/usr/portage/app-portage/eix/eix-0.6.4.ebuild merge

Please remember that after all, you'll have to update your PATH variable
like,
Code:
export PATH=$HOME/$FAKEROOT/usr/bin:$PATH
so that you programs come first in the PATH search line.
This way you can install and uninstall packages safely. Dependencies are always a problem, since you have a quota in you $HOME, a bigger one...
It should work but not without some effort. I really don't know a better approach but I am rather n00b.

Well, hope it helped...

P.S.:
This kind of install is exactly as the pkgsrc package system.
You can untar it in /usr and it creates a pkgsrc dir. You bootsrapt it and it is ready to use.
You just have to
Code:
cd pkgsrc/category/program/
and
Code:
make install clean
and the program is installed to the pkgsrc dir considering some (I really don't know how much) of the programs and libraries you have installed in you root filesystem.
So it doesn't touch ANY of the root filesystem you had prior to installing pkgsrc to you /usr dir.
To use the pkgsrc programs all you have to do is to update your PATH as above.
This might not be accurate because I've tried it only a couple of times...
