From a9d548bf771ae8011ed0d9862184980599dde9a1 Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Wed, 17 Feb 2021 14:09:28 -0500 Subject: [PATCH] Change source path resolution for volume copy-up Instead of using the container's mountpoint as the base of the chroot and indexing from there by the volume directory, instead use the full path of what we want to copy as the base of the chroot and copy everything in it. This resolves the bug, ends up being a bit simpler code-wise (no string concatenation, as we already have the full path calculated for other checks), and seems more understandable than trying to resolve things on the destination side of the copy-up.
