so basically (just lemme know if i can do this in dutch) what you want
is this: you want to have a drake install which you want to run by
itself at home and under vmware at work. but because some of the
settings will need to be different under vmware than when drake is
running on its own, you want to have two partitions with different
settings, and mount the appropriate one.

in principle, yes, if you make sure only one gets mounted. (if you
mount them both, only the second one will be accessible.) if you can
set up the boot process so that it determines how it is running before
it mounts everything in /etc/fstab, you can mount the partition you
need.

should be the same, AFAIK. config in /etc/rc.d/ or /etc/init.d, and
additional files such as /etc/hosts, /etc/HOSTNAME etc.

personally, i think i would set things up a different way. there are
really only a few config files that need to be different, so if you
can determine early on in the boot process how you're running, i would
create multiple versions of the config files that need to be
adjusted. then, right after all file systems are mounted, you can
issue a few mv or cp commands that make sure the correct config files
are in place. (e.g. put an XF86Config.vmware and an XF86Config.bare in
/etc/X11, and then do `cp /etc/X11/XF86Config.<option>
/etc/X11/XF86Config' in the boot process.

this way, if you find a config file that's not in /etc, but does need
to be adjusted, you can easily do so without "unsharing" the entire
directory it's on.

if there is no way to tell whether you're booting in vmware or bare,
you have a problem. perhaps you make two root partitions, sharing as
many dirs as you can. it should be possible to share /opt, /usr and
/home (make sure all users and groups have the same UID/GID on both
installs), and perhaps /var, /tmp, /bin and /sbin as well. but this is
only a wild guess...
