I have had this occur sometimes when the root partition is not mounted as root. (eg /mnt). I don't really know why, but one way around it is to boot off another device initially (tape or NFS) using the -a option (b -sa), then when it asks the question for root and swap, give the local disk (sd0a/sd0b). Once booted, then installboot works fine (installboot -lv /boot bootsd /dev/rsd0a).
