running freebsd completely from memory : possible?

[Mayuresh Kathe]

hello, is it possible to run freebsd-12 completely from memory?
basically the system would boot off my 'ssd' and get loaded up fully in 
memory and run from there and only write back to the 'ssd' on shutdown.
my current use-case involves learning to develop under freebsd using c89 
and i have a quad-core intel i5 at 2.9ghz with 16gib of memory under a 
lenovo thinkpad.
i don't run a 'gui' and browse the web using lynx and intend to work 
with emails using mailx, fetchmail and sendmail (in a personal user 
configuration).
