[gentoo-dev] Virtual for tftp server

[gentoo-dev] Virtual for tftp server

[Maxim Koltsov]

Hi,
Assuming we have a package, that want to have any tftp server on
system, no matter which one exactly, what must we set in DEPEND? I
think creating virtual for tftp server would be nice.

Sure, if there are multiple packages that just want a TFTP server,
rather than a particular TFTP server.

I'm going to add such a package to the tree tomorrow,
http://bugs.gentoo.org/show_bug.cgi?id=365605. Can you write ebuild
for this virtual, because i'm not familliar with new-style virtuals
yet?

Just create an package "virtual/tftp-server" that has RDEPEND="|| (
net-ftp/A net-ftp/B ... )" where A and B are the various tftp server
implementations.

If it doesn't care about what the tftp server is, presumably that means
that the package itself doesn't actually use the tftp server (and if
it did call the tftp server, it would need to know the syntax for each
individual package, so it wouldn't be a virtual). So why would it be a
DEPEND?

Since suggested dependencies don't exist yet, what's wrong with just
elogging a message suggesting the user install a tftp server of their
choice?

I meant RDEPEND, sorry.

I think this is uncomfortable for user.

i dont think so.  i cant see RDEPENDing on a random tftp server being
terribly useful here, and it certainly isnt a requirement.  elog it
and be done.

Ok, please take a look at net-misc/ris-linux. It's used for network
installing windows, therefore user will need tftp, samba and friends,
so i added them to RDEPEND for convinience. Do you think we must ask
user to install them by hand by elog message?

If it's only few (let's say not more than three) packages that need
the dependency, they can easily use || ( ) in {,R}DEPEND. I wouldn't
create a virtual in such cases.
