Anyone can explain this to me?
| Quote: | [15:44:59] root@fujitsu /home/peratu # equery depends dejavu
* These packages depend on dejavu:
virtual/ttf-fonts-1 (media-fonts/dejavu)
[15:45:45] root@fujitsu /home/peratu # emerge -a --depclean
* Depclean may break link level dependencies. Thus, it is
* recommended to use a tool such as `revdep-rebuild` (from
* app-portage/gentoolkit) in order to detect such breakage.
*
* 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.
*
* As a safety measure, depclean will not remove any packages
* unless *all* required dependencies have been resolved. As a
* consequence, it is often necessary to run `emerge --update
* --newuse --deep @world` prior to depclean.
Calculating dependencies... done!
>>> Calculating removal order...
>>> These are the packages that would be unmerged:
media-fonts/dejavu
selected: 2.32
protected: none
omitted: none
All selected packages: media-fonts/dejavu-2.32
>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.
Would you like to unmerge these packages? [Yes/No] |
If I have installed virtual/ttf-fonts, and that package depends on media-fonts/dejavu, so..., why portage wants to remove media-fonts/dejavu?
Thanks! |

/usr/portage/virtual/ttf-fonts/ttf-fonts-1.ebuild
That file contains a logical OR of dependences:
| Quote: | RDEPEND="|| (
media-fonts/dejavu
media-fonts/ttf-bitstream-vera
media-fonts/liberation-fonts
media-fonts/droid
media-fonts/freefont-ttf
media-fonts/corefonts
)" |
That means you can satisfy the dependences with, at least, one of that packages. One, two, or more...
I have other machine with sys-apps/portage-2.1.9.42 . In that machine portage doesn't want to remove media-fonts/dejavu, and I have installed media-fonts/corefonts too. So, I satisfy the dependences with two packages.
But in this machine I have sys-apps/portage-2.1.10.3, and I satisfy virtual/ttf-fonts dependences with the same two packages, media-fonts/dejavu and media-fonts/corefonts. But in this machine portage wants to remove media-fonts/dejavu. So, I understand that sys-apps/portage-2.1.10.3 only wants ONE package to satisfy the logical OR dependences. And for sys-apps/portage-2.1.9.42 it doesn't matter if you satisfy the dependences with one, two or more packages.
Am I right? |

I'm not an expert on Portage internals but I believe you've understood the situation correctly. I've noticed the same thing: that recent versions of Portage are doing a better and better job of keeping the system in good minimal trim, sometimes with non-obvious results.
If you want to keep media-fonts/dejavu, you know the proper solution, right? Add it to the world set: | Code: | | emerge --noreplace dejavu |
