Yes, that's totaly correct.

Here is the steps for the archives if the question comes up again:

edit crunch.conf and add

progs newfs
ln newfs mount_mfs

I mount my ramdisk like this:
/sbin/mount_mfs -s 32768 -T ramdisk dummy /usr/local

where my /etc/disktab entry for ramdisk looks like this:

ramdisk:\
        :ty=mfs:se#1024:nt#1:rm#300:\
        :ns#32000:nc#1:\
        :pa#32000:oa#0:ba#4096:fa#512:\
        :pc#32000:oc#0:bc#4096:fc#512:
