Question related to answering the above using the

PEX_EXTRA_SYS_PATH

method: How do I get the temporary chroot? The

repl

code seems to create a

temporary_dir

from

contextutil.py

. Is this a chicken and egg scenario where I can't build the pex and imbed the env variable without first have a tmp dir? Or is this something that can be defined after the pex is made and supplied at runtime?
