Modules And FIles

I have a module defined in modules file as follows:

my-module     dir1/dir2/dir3

dir1 is in CVSHOME

i have a file in /etc/myfile that I would like to add to this module,
I am not sure how to do that??

if i cvs co my-module, cvs creates a sandbox for me to work in, but
then I have to copy /etc/myfile into that sandbox and run cvs add
myfile. i would prefer to leave the file in /etc and then run
something similar to cvs add /etc/myfile my-module.....
