Indeed, it's dangerous if you don't know what you are doing.

Most overlays are safe, but there are several that could be a big pain if
misused.

About the fvwm thing... well, the easiest thing I can think of would be
this: don't use layman. Sync the overlay into your home dir, for example:

cd ~
mkdir svn
cd svn
# for the next command you need subversion, emerge it if
# you haven't done it yet
svn http://svn.engelkotzen.net/public/devnull

Now you have the overlay in your home, but it is not too useful there. So,
you need to make your personal overlay, edit /etc/make.conf, and add this
BEFORE the other line I gave you above:

PORTDIR_OVERLAY="${PORTDIR}/local"

Now, this:

cd /usr/portage
mkdir local
cd local
mkdir x11-wm
cd x11-wm
ln -s /home/i92guboj/svn/devnull/x11-wm/fvwm .

Now, you have your own personal overlay, with only one package, but that
package is into your home dir. The contents of your /usr/portage/local/x11-wm/fvwm
overlay will be a link to the real contents in your home.

What is the advantage of this? Well, portage now can see your new fvwm package,
and you can update the devnull overlay with a simple command, but the rest of
package into devnull will not interfere with your system.

To update the overlay, you do

cd ~/svn/devnull
svn update

And you will have the latest stuff in that overlay (but only the fvwm stuff, or
whatever you link into your local overlay will be used.

You can as well just create the /usr/portage/local/x11-wm/ dir, set up the make.conf
as I told you above, and then cd into /usr/portage/local/x11-wm/ and then 
do "svn co http://svn.engelkotzen.net/public/devnull/x11-wm/fvwm" to update
only that little bit of the tree.

This second way can be more convenient because you save some bandwidth, since
you only download the stuff that you want.

As you see, you have many alternatives. The problem with either of this,
is that you are the responsible to update the ebuild when necesary via svn.

If you have questions, just ask.
