yes, quite possible.  we don't do ufs2.

Would it be possible to make FreeBSD and DragonFly to coexist on
my FFS partitions?
yes, but probably you want to pick different partitions for each OS :)

(At boot time i have to pick the correct bootloader and kernel etc.,
 but this is not too hard...)
you should rather pick the right partition/kernel.  the binaries are not compatible, so you wouldn't have much luck sharing them.

How about making an extra root partition, e.g. /dev/ad0s2g, for DragonFly,
then mount my user stuff from there?
Yes, but be sure to also put there /usr and probably /var.

What you need to do is:

1. install freebsd, leave a partition or two for dragonfly.
2. use ufs1 for all data you want to share (probably /home).
3. install dragonfly to the remaining partition(s)
4. from both OS, mount /home
5. to boot one or the other you can either use loader and set currdev/kernel to one or the other root partition
6. or you use grub to load different loaders.
should work this way

cheers
