I would already su before unpacking the tarball. There is no reason to be 
root at all during any part of the installation as long as the user doing 
the install belongs to a group that has write access to /bin and the other 
installation directories.

I haven't tried but I don't think that a missing home directory (and I 
think that's what it would look like) is fatal. Not unless some program 
tries to access it by reading from /etc/passwd and I think install scripts 
won't do that.

I think you can have a user without a password, that only root can su to  
and where logins with that id are impossible. I don't remember how you 
have to write that into the /etc/passwd, though.

No. The dir will need to be writeable by the group that bash belongs to.
