So I think I noticed a safety issue with the new symlink feature. It seems like you can call 
export
with the symlink flag and it rightfully says it puts an immutable venv in place. However, if you do this without clearing the export that didn't use the symlink, you still have 
pip
and 
python
in the 
bin
directory. Is that expected?
I was also seeing some weird behavior so I nuked 
named_caches
and then ran the export again and it linked to a directory that I just deleted
Using 
--no-local-cache
ran things up properly
oh interesting. Following the 
--no-local-cache
, a subsequent 
./pants export
symlinked back to a removed directory

~/devel/monorepo (move-dev-reqs)$ ls ~/.cache/pants/named_caches/
ls: cannot access '/home/nathanael/.cache/pants/named_caches/': No such file or directory
even more concerning. Removing the entire cache contents still points things back to this no-name directory
going to move to a bug ticket
