Just choose to install the FreeBSD Boot Manager, and you'll be fine doing this. I do this so that my laptop always has a runnable -stable, then run -current for day-to-day use. My laptop is a production machine for me, after all. My disk is divided a little differently, however: pedicular~;dh Filesystem Size Used Avail Capacity Mounted on /dev/ad0s3a 197M 62M 119M 34% / devfs 1.0K 1.0K 0B 100% /dev /dev/ad0s3f 4.5G 1.1G 3.0G 27% /usr /dev/ad0s3e 246M 4.6M 222M 2% /var /dev/ad0s2a 246M 39M 187M 17% /stable /dev/ad0s2f 4.4G 1.6G 2.5G 39% /stable/usr /dev/ad0s2e 246M 27M 200M 12% /stable/var /dev/ad0s4e 26G 7.3G 17G 30% /shared pedicular~; Note the /shared partition, that takes up most of my space. The actual OS is small; there's no reason why things such as the ports tree, /tmp, /usr/obj, and my home directory cannot be shared between the OSs. /shared contains a hand-crafted duplicate of selected portions of the file tree, and I use a lot of symlinks to redirect directories more-or-less transparently. It's tedious, but easy.
