Hi, is this for source mirrors or rsync mirrors?

Hi mirrors,
Historically, our CVS-to-rsync process was overly enthusiastic about
updating timestamps on files, even if they hadn't changed.
With the new Git-to-rsync process, we've run into a few cases where the
mtime is not represented with sufficiently high accuracy to catch all of
the changes, and as a result changes are being missed.
Can you please alter your rsync cronjobs to include --checksum in the
commandline? All Portage calls will be including --checksum in future as
well.
A decade ago, we didn't include --checksum in the calls, as the CPU
power available was considerably less; however systems have improved
tremendously since that time.
I have updated the official mirroring wiki page, and if it's been a long
time since you reviewed your scripts, I encourage you to review it:
