RCS do one directory RCS by directory.
thats mean that for /etc for example you will have one directory RCS for all the
files you have under version in this directory.
If you register a file in a subdirectory of /etc you will have a RCS directory 
in
this subdirectory ....etc..
If you use RCS for file in /etc think at unlocking the files that can be 
dynamically
modified by the system.
But another time, if you want to put under version a big set of files like /etc,
use another version system.
CVS ==> bof...
SVN ==> good but a central repository.
mercurial ==> very good, own repo, you can use it with dvc.
git ==> seem to be the more advanced, work with dvc.
bzr ==> seem good, never tried, work with dvc.

With mercurial, if you want to put under version all /etc,
just do while you have cd in /etc:
hg init.==> thats done, all files in /etc and all subdir are under version!
