Quoting Florent Thoumie <[email protected]> (from Mon, 29 Mar 2010 09:10:54 +0000):
I mentioned getting rid of those pesky @*exec lines a few years ago,
but this was met by quite a lot of objection.
I still think it would be a good change, assuming that we provide
equivalent (or better) features:
- Configuration files should be marked and automatically dealt with by
the infrastructure, not by esoteric commands.
- Subroutines for shell scripts should be provided along with
pkg_install, or be installed by a third party port (users/groups
creation comes to mind).
- Scripts should be automatically picked up as you mentioned. We're
trying to shove most targets in pkg-install, but it probably would be
best to split it (preinstall, postinstall, predeinstall,
postdeinstall). Good thing is, this doesn't require any change in
pkg_install since it's already supported.
One of the added bonus is that some code that appears both in Makefile
and pkg-plist will only be in preinstall/postinstall scripts.
Given that a lot of the @(un)exec is comming from ports/Mk/bsd.*.mk,
and that you can detect if there is already a pre-/post-install script
in bsd.port.mk, it should be not so hard for the people which propose
those (IMO good) ideas to come up with a patch for bsd.port.mk which
generates pre-/post-install scripts with appropriate commands and does
not add the @(un)exec to pkg-plist for those ports, which do not have
a pre-/post-install script. It could serve as a proof of concept and
would show more clearly what you have in mind. Done nicely, it also
allows to keep a lot of the stuff in the Makefile and only write such
scripts by hand if absolutely necessary (think about e.g.
"CREATE_USER=name1:UID1 name2:UID2" which would already cover a lot if
not most use cases).
Bye,
Alexander.
