syncrepo: Drop --temp-dir option as unneeded · 4fe427a2Evangelos Foutras authored
Using a temporary directory outside of /srv/ftp was meant to protect against incomplete files from being synced by downstream mirrors. It does not achieve this to much effect though; each file gets uploaded to the temporary directory but then immediately moved under a .~tmp~ directory at its target location (.~tmp~ because of --delay-updates, otherwise the file would be renamed to its final path). The `--delay-updates` option by itself sufficiently protects against temp files being transferred to downstream mirrors; when used by the receiver, it automatically adds an exclude rule for ~.tmp~, behaving exactly like we want it to. As such, the `--temp-dir` option doesn't provide any further benefit and can be removed.
