Change
We already had a single retry after a 250ms wait for our
rename
of the installer to make it shell actionable with the correct extension. This change makes it try every 100ms for 500ms, then usecopy_file
with a hard link option as a fall back.The hard link is better than a true copy, as it won't take up more space. But it won't get cleaned up on a successful install either.
Long term we should put in some background cleanup to remove old installers that were abandoned due to failures.
