Hai David, 

What you want is possible, i would do something like this. 
I've not tested it but read it, its a good pointer howto do this. 

Debian used systemd.  Close your eyes Rowland.... ;-) 
Im still learning things about systemd, so if some sees things that needs to be corrected please tell us. 

To remember! Files in /etc/tmpfiles.d override files with the same name 
in /usr/lib/tmpfiles.d

so knowing this  .. 
cp /usr/lib/tmpfiles.d/samba.conf /etc/tmpfiles.d/samba.conf
and add to this file 
d /run/samba/varcache 0755 root root -
d /run/samba/varlib 0755 root root -

This solves the problem of the needed tmpfs folders

Now you problely also want to backup the content of these 
when stopping samba and put it back when you start samba. 
This might be bit faultly, and may need corrections. 

Create the samba2ram.service folder to add this service file. 
chmod 664 /etc/systemd/system/samba2ram.service
add something like this to the service file. 

Description=Samba tmpfs copy/restore to ramdisk



Example very simple copy script. 

if [ "${1}" = "start" ]; then 
	cp -R /var/cache/samba /run/samba/varcache
	cp -R /var/lib/samba /run/samba/varlib

if [ "${1}" = "stop" ]; then
	cp -R /run/samba/varcache /var/cache/samba 
	cp -R /run/samba/varlib /var/lib/samba 

and enable the service.
systemctl enable samba2ram.service
test : systemctl start samba2ram.service
or reboot the system.
