emerge --depclean wants to remove nano, why?

[310354]

Hi,
I can't understand why emerge --depclean wants to remove nano (and maybe other unwanted things; I'm not able to judge since my knowledge isn't so wide). Please check the following:

Code: Select all

sudo emerge --depclean --ask

 * 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!

nano has been removed from @system a while ago. If you want to keep it, just add it to world:

Code: Select all

emerge --noreplace app-editors/nano

I don't know what to make of the output "app-editors/nano is part of system", this has not been true for months. Except maybe if you do not have any other editor installed.

I doubt the other packages have to do with nano, just try it after adding nano to world.

I did emerge --depclean after adding nano to world favourites as you suggested. The problem is that it removed the icon pack in use, so I had to reinstall it. Now I am a bit worried, because if emerging --deplcean had removed an unwanted thing like gnome-icon-theme, it could also have unmerge necessary packages concerning perl (in my case). The question is: why depclean doesn't know important packages that should not be removed?

tant0c1b0,

Its getting better, a long time ago it removed glibc for me :)
There is a warning about reviewing the package list.

I always use either the pretend "-p" or ask "-a" option for emerging, revdep-rebuild or depclean before allowing it to run willy-nilly.

Moved from Portage & Programming to Duplicate Threads in favor of [topic=883019]--depclean wants to remove nano![/topic], which explains the whole rationale and the work-around.
