By default now, geom creates an ufsid label on its ufs partitions (similar idea to linux's uuid scheme). If you choose to not use it (let us say, for instance, as we can clearly see, as no-one could disagree (and 30 other inane Chomskyisms)) by mounting your partitions via their respective bsdlabel names, geom kindly removes them. There has been some debate as to whether this should be silent or not (I think in freebsd-current@), since it is perfectly safe to ignore. It is perfectly safe to ignore. -- -- _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
