I sometimes wonder it init could just execute MAKEDEV with a flag to
create an appropriate filesystem?
I don't think there is anything in init that couldn't be done from a
shell script - but, OTOH, I haven't tried to write it.
The only place the memory footprint may matter is in the small install
media - which is why the size of the mfs filesystem is limited.
For mfs, the cost of each device inode is (about) 128+16 bytes.
