Could anyone explain what a "chroot zap" is (from the 'effective caching' feature)? Googling it just brings me to the same page.

It means: remove the chroot folder (safely, with umounting everything first). You can do it with "pmbootstrap zap", it will ask interactively, which chroots you want to delete.
