Linux emulation - chroot always?

[Swift Griggs <swiftgriggs%gmail.com@localhost>]

When a Linux-binary runs, what does it "see" in terms of the root file 
system? So, for example, if I run 'ldconfig', does it see Linux libraries 
in /emul/linux/lib or just "/lib" ?

Also, how does this play out when I want to run Linux binaries from my 
home directory? Ie.. if I wanted to run foobar.exe and it expects to find 
some shared lib in /usr/local/lib does that need to be relative or 
absolute?

What about 32 vs 64 bit binaries, is there any automatic translation or 
chrooting for /emul/linux vs /emul/linux32 ?
