Variable passed from one script to the next

I have a script that sets up and creates a chroot environment. Then copies the secondary over into chroot & continues. Question is, does the previous variables declared in the first carry over? I do know that its a different environment being chrooted. Just curious... before I start re-writing my secondary script.

Code:

export FOO=BAR
chroot / bash
echo $FOO

answer:

Code:

BAR

If you don't want that, use env -i:

Code:

export FOO=BAR
chroot / env -i bash
echo $FOO

answer:

Code:
