 |
|
There I had to reinstall my gentoo system (root partition crash) I had to think hard on what to install, what pacakages did I need on that machine. Also I was thinking how I could do this better the next time. So I started to write down all packages that I installed in one file. Then I added the USE="" statement and some other variables and commands to this file. I ended up making the file machine readable (xml like syntax).
Here is a part of my install file (not complete) | Code: | <?xml version="1.0" encoding="UTF-8"?>

This file describes what needs to be done after a stage3 install
on my machine to get it to the level I want it.
In principal this file can be used to (re)build any machine to the same
instalation level.
syntax:
<Gentoo "description">
<file "filename">data</file>
# data will be added to the named file.
# If file does not exists, it will be created
<set "setname">package-name</set>
<set "setname">
package-name
package-name
package-name
<commance "command"> arguments </command>
</set>
<command "command">arguments</command>
run "command"; supported commands are (limited set for security reasons): adduser, groupadd, rc-update, source
</Gentoo>
-->
<Gentoo "photo station">
<file "/etc/make.conf">
USE = "exif hal dbus tiff -arts -eds -esd -kde -gnome -ipv6 -mssql nptl nptlonly bash-completion X gtk qt3 alsa oss bzip2"
# video card is Matrox G400:
VIDEO_CARDS="mga"
#build in via VT82C686 audio:
ALSA_CARDS="via82xx"
</file>
<file "/etc/portage/package.use">
# cd/dvd burner, without sound/music support
app-cdr/k3b -encode -vcd -alsa dvdr
</file>
<set "base-extra">
sys-process/vixie-cron
app-admin/syslog-ng
<command "rc-update">
add syslog-ng default
add vixie-cron default
</command>
<!-- my favorite editor for system tasks, please no flame wars -->
app-editors/vim
app-admin/sudo
sys-apps/fbset
app-shells/bash-completion
</set>
....
</Gentoo>

With a complete file like this and a small script, everyone would be able to install, on any machine, the same configuration (after doing a stage3 on that machine)
Of course a lot more posibilties are now open. Some default configurations could be defined and be shared between gentooers. If you want, for example; a proven kde, or xfce desktop, or a gaming instalation, etc. Select the right setup file and start installing!
Maybe you find it less interesting, less educative, etc, but after installing 3 machines by hand I want to automate this!
What do you think, is this interesting idea? Should we start developing a script to support a installation method like this? Please do not forget, it is an installation method for adding packages after you have done a stage 3 install. So in now way comparable with any other distribution. And you keep all the freedom, because you can make your own setups, or adapt the ones that do exists. |

| I've seen something like this already. You go to a machine that you like, type something, and get like a list of all packages there. Then you go to another machine, and it will re-emerge the whole stuff. I've seen it and seemed to be quite mature, although I haven't tried it. The guy had a dedicated website for that as well. Search in the forums/net, it has been done! |

| Thanks, i will do a search. But the way you describe it, it sounds different. If you get all packages from a machine, the list will be very long due to all dependecies taht have been installed. What I am proposing is to only list the main packages and portage will emerge all the other stuff you need. The advantage is that such a list is much easier to maintain. Plus I am adding special commands to start services etc. |
