In operating systems like Debian, Gentoo, FreeBSD, you pratically never 
install something for one user, you always install libraries in a generic 
location (/lib, /usr/lib, /usr/local/lib, etc) as well as binaries for 
everyone to use and that is what I would like to achieve by making a deb out 
of a plt.

Yes, as long as no other task is needed to be done (MrPersist needs some C 
code to get compiled for example, and I've seen a plt wanting to *modify* 
another file, am I mistaken about that ?)

So, I could something like:
 setup-plt -l /tmp/temporarycollection
and then repackage those files to be put on the real collection ?
Won't any path be hardcoded when I do that ?
Do I have to set up /tmp/temporarycollection in any particular way ?

Would this find the user's plthome or the general one ? I'd need the general 
one.

What do you mean ? Can you elaborate on what are the consequencies of those 
actions.

Thank you.
