No! Your situation is much worse! The FreeBSD boot code *always* expects the root filesystem to be on partition 'a' of the *first* BSD slice on the disk. Now, what used to be the first BSD slice on your disk now became the second (because there's a new BSD slice in front of it), so the boot code cannot find the root partition. Having two FreeBSD slices on the same disk is a mess. Avoid it at all costs. If it cannot be avoided, you should probably make a new installation into the first slice, then copy important things from the original root filesystem to the new one, modifying /etc/fstab to use the original partitions. > > -- > --------------------------------------------------------------------- > Generic Duck and Weave: > The above expressed views do not reflect those of BMC Software or > their subsidiaries unless otherwise noted. > --------------------------------------------------------------------- > Programming today is a race between software engineers striving to > build bigger and better idiot proof programs, and the Universe trying > to produce bigger and better idiots.
