I installed stage-3 2007.0 and am now trying to configure
it to my liking. For example, I dislike nano and would like
to use vim instead. vim (among other editors) provides
virtual/editor. So I thought, that I could add
These are the packages that would be merged, in reverse order:
Calculating dependencies... done!
[ebuild N ] mail-mta/ssmtp-2.61-r2 USE="-ipv6 -mailwrapper -md5sum ssl" 53 kB
[ebuild N ] net-mail/mailbase-1 USE="pam" 0 kB
Total: 2 packages (2 new), Size of downloads: 53 kB
So, what am I doing wrong with regards to virtual/editor? I know
that I could just install app-editors/vim and be done, but I'd
like to know why emerge virtual/editor doesn't work the way I expect
it to work (or why my expectation is wrong).

Emerging virtual/editor installs nano - why?
Hi,
there is a virtual/editor package in the tree, that selects nano as the
default choice. A virtual/mta package does not exist ATM.

How does it do that? How do I make it select something else?

True. There are just packages which PROVIDE virtual/mta.

I think you simply emerge vi (or vim or emacs or joe or whatever) and
then portage will no longer try to emerge nano (or any other editor).
EG:
emerge -C && emerge vi && emerge world

*Yes, I know. That's one way. But why am I able to "preselect"
the virtual/mta by editing the virtuals file and why can't this same
thing be done for virtual/editor? Basically, I'd like to *preselect*
what should be taken as a virtual.
Best regards,
Alexander

profile/virtuals is for old style virtuals only. editor was converted to a new
style virtual. New style virtuals are just ebuilds was an any-of runtime
dependency on all providers. On initial install portage will choose the first
visible provider that's listed in the ebuild. So either put it in an overlay
or just install the provider you want and let that satisfy it...

It's done by using the RDEPEND variable inside the virtual/editor
ebuild.
That says that the package needs any of the packages in parentheses to
run. If none of them are installed, the first one in the list is
selected to be installed. (AFAIK)
You can read about this in "man 5 ebuild", on [1] and the glep posted
before (that should be an particularly interesting read).
> How do I make it select something else?
I would say you don't. Just emerge the package you want (as you already
mentioned).

Thx. Understood.

Okay. And why am I able to preselect the mta the way I
demonstrated?

Thx. Understood as well.
So the expectation should be, that it's not going to be possible
to preselect an mta the way I've shown, as soon as virtual/mta
is converted to a new style virtual.
Is that right? Is there work going on to change all the old
style virtuals to new style ones?
I don't know, but from a user perspective, these new style virtuals
offer less flexibility. I've read the GLEP, but don't quite understand
why something with lesser flexibility has been introduced. I understood,
that old style virtuals might have had some performance problems for
portage.
Well. I guess there's nothing that can be done about it.
Thanks,
Alexander

You are right except for the fact that virtual/mta will not be converted any
time soon (if ever). Old style virtuals allow their providers to block all
other providers by blocking the virtual. This isn't possible with the current
format for new style virtuals so it isn't going to happen. editor didn't need
that feature and thus could easily be converted...
