[gentoo-user] HOWTO stick a package

[gentoo-user] HOWTO stick a package

[Andrew Gaydenko]

Hi!

Currently I have xorg-server-1.6.1.901-r4 - as far as all newer ones don't 
work for me (I mean GL-related things with my intel graphics), while first one 
makes my son happy with few GL games. So I have masked all xorg-server 
versions which are later rather one currently installed.

Today after syncing the portage tree I was surprized this 1.6.1.901-r4 version 
is dropped, and emerge suggests to downgrade to 1.5.x, while I want to stick 
to currently installed. 

How to say portage to "keep this as is"?

Find the ebuild in /var/db/pkg/category/package
Copy it to your personal local overlay
Configure make.conf to include this in PORTDIR_OVERLAY
Mask anything later than that version

All standard stuff, documented at length in gentoo docs. Search for "overlay"

Thanks, it works - just created Manifest also.

It's pity that portage doesn't support the .deb concept of pinning. I know you 
can always achieve the same effect with masks, but it would be nice to be able 
to say "hold package XYZ at current version" and be done with it. It happens 
often enough to be useful.

You might want to take a look at man 5 portage, in particular, the
section on /etc/portage/profile/package.provided.  If you list a full
package atom with a version in there, portage will not bother you about
upgrading that package, and  you do not have to keep the ebuild around
in a local overlay.

Does this do what you are trying to do?

This little snippet from --depclean is enough to make me never use 
package.provided with a package from an ebuild:

# emerge -a --depclean

 * Always study the list of packages to be cleaned for any obvious
 * mistakes. Packages that are part of the world set will always
 * be kept.  They can be manually added to this set with
 * `emerge --noreplace <atom>`.  Packages that are listed in
 * package.provided (see portage(5)) will be removed by
 * depclean, even if they are part of the world set.


AFAIK, package.provided is for use with apps that are in portage but for 
whatever reason the user has decided to install them by other means. 
package.provided is a way to satisfy deps of that package without having it 
installed via an ebuild. The solution you propose does require installation 
via an ebuild.

I always just use /etc/portage/package.mask

e.g.:

>media-libs/mesa-7.3-r1

masks anything greater than that version. 

(for me, 3D/dri does not work with my Intel chipset (G35) for mesa
greater than that).

That's what Andrew already did. But now the specific version he needs is no 
longer in portage, so portage wants to downgrade. Maybe masking lower 
versions also would do the trick?
But putting the ebuild into the overlay is the cleanest solution.

Oh, I see. Well, regarding the Intel graphics (I have the same thing) I
found that it is related to the mesa version and X configuration,
anyway, not the X server version. I currently have the latest X server
but with mesa-7.3 and it works fine.
