Some way to protect packages from --depclean?

Hi all.
My problem is simple: when I launch "emerge --depclean", I don't want earlier versions of sys-kernel/gentoo-sources to be in the removal list. Is there some way to do it? maybe some way to protect packages from --depclean-ing? (if there aren't, I'll file an enhancement request in Bugzilla)
Note that sys-kernel/gentoo-sources is already in my /var/lib/portage/world file.

Yep. Just make each version of gentoo-sources explicitly part of world:

Good point. No it's not.

I agree, I've hade the same issue for a long time. It would be good to have a package.keep file in etc/portage/profile/ so you could protect files (with versions perhaps) from depclean. Then you would have all that stuff in one place, instead of having to edit the world file.

Btw, why are there so many people in the forums using portage 2.2? It seems like everybody in the forums are running it, even though it is hard masked in package.mask. I do think I was actually running 2.2 about a year ago (or so) since I used to run emerge -uDatvN @world, which is a feature from 2.2, right? The "sets" i mean. But for some reason I'm back on 2.1.7.4 now.

Why is it so common for people to unmask 2.2?

I do trust the maintainers, so I'm not going to immediately say "I agree fully", I assume there is a reason for it being masked. But you do have some points, and I can't wait for it to me unmasked. Maybe I'll do it soon myself, how about tomorrow? :wink:

It really speeds up the builds to run --jobs when I have an i7. I was amazed when I tried it earlier this year. --keep-going is also kick-ass!

Is it possible to get a maintainer to comment on this? The unmasked/hardmasked thing I mean? Preeetty pleaaaaseee...

I haven't tried it, but won't package.provided do what you want? Or will the
package still be removed, just not replaced?

I'm now updating to portage 2.2-*, let's keep our fingers crossed and hope it works out for the best!

azp,

If your world file is "huge", then that may mean that it contains some unnecessary entries. Whatever package that is a dependency on any other package or set is not needed in the world file.

Most of the time the world file becomes cluttered as a result of not using the --oneshot option, when re-emerging something that is a dependency.

For example; nowadays, I suspect that many users have x11-drivers/ stuff in their world files, which is of course totally unnecessary.

But, even a clean world file can grow rather large. So your point is valid.

Vim? Emacs? Nano?? What text editor do you like? One of the regular maintenance activities with Gentoo is to look through the world file to delete entries you didn't mean to end up there. In fact, Portage has been criticized because the default action when you run emerge is "install" as opposed to "update". Many think that's backwards.

I believe the reason portage 2.2 is still without keywords is because there are still many bugs against the 2 big features it adds (sets and preserve-libs) (bug 144480 and bug 240323, respectively). A lot of these issues will probably be resolved by EAPI-4-slot-abi, but who knows. Also, part of the reason most of these bugs still exist is portage 2.1 still needs updates to support new stuff so it's not like 2.2 is the only branch where development is happening...

I've been tempted to manage kernel sources by hand, probably less trouble than managing it via portage, ebuild can fetch the tarball.

I've been out of the loop for quite some time now, so this is just an educated guess, but it used to be that Zac considered sets not ready for prime time without dependency based set operators (rather than the string based operators I implemented back then). And preserve-libs has another set of issues causing hard-to-figure-out problems annoying users that expect a silver bullet solution to the linking problem (which IMO will never exist).

Hi there,
I've set the "--noreplace"option to some world packages, however, can remember their names anymore.
Is the anyway portage command or emerge option to recover them?
Thanks in advance

John R. Graham · Posted: Thu Aug 30, 2012 4:34 pm Post subject:

--noreplace isn't an option that is set on a package. It's just an ephemeral instruction to the package manager not to build the package if it's already installed. Other actions still occur, namely, adding the package to the world set if it isn't already.
