* Yes. Another option is /compat/linux/etc/redhat-release. I explicitly
* kept that file for these purposes (but don't care if it's not used :-).
* If such is needed in the future we can parse that file for the version
* number and complain if it's not appropriate for the port.
It might be better if you change the filename to indicate different
versions if the need arises. The *_DEPENDS in bsd.port.mk can't read
the contents of the file. (Something like "redhat-release-6.1".)
* I just looked in /usr/ports/devel/linux_devtools and it contains the
* following dependencies:
*
* RUN_DEPENDS =
* ${PREFIX}/etc/redhat-release:${PORTSDIR}/emulators/linux_base
*
* where PREFIX .equ. LINUXBASE in the patch.
I see.
* At this time I don't see the need. If new evidence pops up, we can
* always decide to do it then.
Ok. NO_MTREE for now then.
* Yes. I was thinking about why and when a port would need ldconfig and
* concluded that it likely doesn't need ldconfig until after it has
* installed the libraries. This of course means that a dependency on
* ldconfig for the build phase is wrong. If a port builds linux binaries
* from source, it depends on linux_devtools and BUILD_DEPENDS should
* contain something like gcc. If it downloads and installs a distribution,
* then BUILD_DEPENDS can be something like rpm, but not ldcondig. The
* install target will need a dependency on ldconfig or libc.so or whatever
* to make sure that linux_base is installed first.
*
* I think that the BUILD_DEPENDS should be empty by default. Only fFr the
* ports that depend on linux_devtools to work (linux_kdump for example),
* something like
*
* BUILD_DEPENDS =
* ${LINUXBASE}/usr/bin/gcc:${PORTSDIR}/devel/linux_devtools
*
* will do the trick.
You mean there aren't any ports that depend *only* on linux_base that
needs the libraries (or anything else that it contains) for building?
For instance, isn't there something that will run its own binary
installer, that needs shared libraries?

*
* Works for me.
Ok.
