 Posted: Wed May 23, 2007 7:49 am Post subject: [SOLVED] moving gnome (or gnome-light) out of "world fi |
 |
|
I want to remove some of the packages that came along with GNOME.
I'm using gentoo for a long time now and I know that I could just do
something like this:
| Code: |
emerge -C "application_name"
|
Seems right, but it's not!!
You see, the next time I will upgrade world, portage will think that it must
install the application I removed (as being a part of the GNOME meta-package).
So, is there a permanent solution to this problem (removing a part of GNOME)??
I guess that I could "edit" the GNOME ebuild, but this is way too hardcore for me!
Apart from that. updating portage will restore the ebuild to the original form (I guess)!
I was thinking of manually removing the "gnome" entry from the world file...
and then (manually again) adding the appropriate entries (for the installed components)...  
Any ideas/suggestions?
Thanks in advance!

Depending on what you want to get rid of i would recommend /etc/make.profile/package.provided or a gnome-light meta with whatever else you need to add on. I guess you considered the latter but still i would prefer that solution since only the really necessary stuff is installed then and those you need for sure. If youremove something in that meta you will probably run into trouble. Same holds for package.provided. You have to make really sure you don't get rid of something that some other package depends upon.
Following is an excerpt from man portage explaining. package.provided
| Code: |
package.provided
A list of packages (one per line) that portage should assume have been provided. Useful for porting to
non-Linux systems. Portage will not attempt to update a package that is listed here unless another pack-
age explicitly requires a version that is newer than what has been listed. Basically, it's a list that
replaces the emerge --inject syntax.
For example, if you manage your own copy of a 2.6 kernel, then you can tell portage that 'sys-ker-
nel/development-sources-2.6.7' is already taken care of and it should get off your back about it.
Virtual packages (virtual/*) should not be specified in package.provided. Depending on the type of vir-
tual, it may be necessary to add an entry to the virtuals file and/or add a package that satisfies a vir-
tual to package.provided.
Format:
- comments begin with #
- one DEPEND atom per line
- relational operators are not allowed
- must include a version
Example:
# you take care of the kernel
sys-kernel/development-sources-2.6.7
# you installed your own special copy of QT
x11-libs/qt-3.3.0
# you have modular X but packages want monolithic
x11-base/xorg-x11-6.8

| Code: | | emerge -C gnome && emerge gnome-light && emerge -p --depclean |
Then as above. Unmerge what you can live without and put it in package.provided to avoid re-emerging. Be sure not to discard any library dependencies.
and running dep -s may also help.
Another way would be to emerge -C gnome && emerge -p gnome-light, then merge all the packages listed manually (omitting gnome-light itself, of course) and then doing an emerge -p --depclean to see what portage wants to ditch.

If you're not using Evolution or anything depending on its data-server, you can also add "-eds" to the USE variable in your make.conf file. Takes a bit of fiddling to really put down, but makes the world smaller!
