Hello, as proposed in http://lists.debian.org/debian-bsd/2008/06/msg00004.html,the primary kernel is now 7.0. It basically means update of freebsd-libs, freebsd-utils and namely kfreebsd-kernel-headers.
In case of a problem, the snapshot with libs and utilities from 6.x is available from http://ftp.debian-ports.org/debian-snapshot/kfreebsd-6.x/ Many thanks to Aurelien for uploads. Please test it and tell us results. Cheers Petr
