Running "portupgrade -nrR <package-list>" repeated until <package-list> stabilised used to also work for just-in-time upgrades like this. Unfortunately "portupgrade -nrR" no longer reports packages that won't be upgraded. There are no longer any "-" entries in the output. I need to see what "portupgrade -nrRf" does before reporting this. > The paragraph you quoted above attempts to avoid that breakage and the > mailing list questions that ensue, by forcing a rebuild of all ports to > begin with. > > -- > Skip > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: Mark_Andrews@isc.org
