sym link question...

[bruce]

hi...

i have a question regarding symlinks. i have my system partitioned 

/dev/hda5    100 /
/dev/hda1    10000 /home
/dev/hda2    30000 /usr

is it possible to create a symlink that would allow '/' to point to
/usr/root. i'm inclined to think you can't but i'm not knowledgeable about
the concept of symlinks within linux....

would you have to copy the dir structure under '/' to the symlink. and
wouldn't this cause a recursive issue/situation?? 

comments/explanations/thoughts would be helpful/appreciated!

thanks

bruce
