Probably the easiest way to do this is to divide your script into two
pieces: one piece runs inside the chroot, the other doesn't. Then you
have the "outer" script invoke the "inner" script as a separate
process. When the inner process terminates, the outer continues, and
since the outer wasn't chrooted, it's now running commands relative to
the outside.

One convenient way to manage this is to have one script that invokes
itself with arguments. Another way is to have two actually separate
script files. It really depends how much work you're doing in each
half.
