beating mergemaster to /etc/rc.d

i know that when i do a mergemaster, i am about to see 666 updates
to /etc/rc.d/*, to each of which i will have to type "qi<eol>".
as it will be over a 9600 baud remote serial console, this is a
pita and causes undue delay for the users.

once i boot the new kernel -sw, is it safe to

   cp /usr/src/etc/rc.d/* /etc/rc.d

and then run mergemaster -cvi?
