I was under the impression that /home was normally writable only by
root and the subdirs were normally only writable by the user who owns
the directory (yes, I know you can set them differently if you want).
I know I wouldn't want joe-the-user creating directory /home/justinpa
to try to confuse justinp whose home dir is /home/justinp.

I suppose they don't. I admit I was thinking in "Embedded" mode, which
normally means single-user to me. Still, it would have to be someone
putting files in a very specific place which should normally be only
writable by a super-user. Of course someone could use security holes
in another program to write the files, etc etc.
I'm not saying this doesn't need to be fixed, just that it seemed like
a big inconvenience for those using OE who couldn't fix the problem.
Then again it seems that someone came up with a hack at least, so....
