Was I dreaming? Well, that should be easy. You just have a new disk, slice, partition and newfs it with a new UFS2 system. Then dump the old partitions and restore them on the new partitions. It is still a matter of creating a new system with new space. You could do it to a spare machine and then once it is all built, do the same back to the old machine and it would all be up-to-date. The new one would be nice and clean then too. ////jerry > -- > Cheers, > Devin > > > > ////jerry > > > > > >> -- > >> > >> Erik Trulsson > >> ertr1013@student.uu.se > >> _______________________________________________ > >> freebsd-questions@freebsd.org mailing list > >> http://lists.freebsd.org/mailman/listinfo/freebsd-questions > >> To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" > > _______________________________________________ > > freebsd-questions@freebsd.org mailing list > > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
