I don't think it's useful. IMO Ports failing to build if their ancestor is installed are buggy (usually they set wrong CPPFLAGS and LDFLAGS and pick up system-wide before local #includes) and should be fixed. I am concerned that such a flag would only be abused as a sort of "I don't mean to fix the port" marker. Stephen has (according to his replies here in this thread) done the right thing and fixed them. However, a simple NO_REINSTALL = yes with the meaning of "deinstall port ancestor before attempting a build" doesn't help: - if files have moved between ports. The former could only be fixed with a REINSTALL_PORTS_GROUP= origin1/port1 origin2/port2 ... or similar (not sure if pkgng would be a good starting point for that) - and/or if deinstall scripts break the system. In contrast to RPM-based systems, this is hardly ever a problem in FreeBSD, as the pkg* stuff doesn't install two versions in parallel if you update with rpm -U. And even if we had NO_REINSTALL, we'd at least need to be able to state a version range, because ports like this can usually remain installed if you just bump PORTREVISION to add a security patch or fix pkg-plist. Or have I misunderstood your proposal now? _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
