Starting with version 1.96+20090826-1 grub-pc uses the wrong fs type for the root filesystem, so your system won't boot anymore. The solution is to change set FreeBSD.vfs.root.mountfrom=ufs2:/dev/ad0s1a into set FreeBSD.vfs.root.mountfrom=ufs:/dev/ad0s1a (bug report as bug#543950) -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurelien@aurel32.net http://www.aurel32.net
