Executing ./try echo hi on mount-fix branch errors out with warnings that every mount point failed to mount as an overlay. It appears that this is caused by failed uid/gid mappings that must occur due to NixOS's wrapper.c. Full command output and contents of the referenced tmp file are included below.
