this doesn't seem like accurate reproduction-
the . directory is not '770' like originally.

nevertheless, i can't reproduce this on any alpine version with the same
directory layout in a container, so indeed, "strace or it didn't happen" is
accurate.

the container build output curiously has a "bash" in the list of packages
installed- so i tried running this from inside bash in case the bash builtins
for this were broken- no difference.
