"PS" == Paul Stewart <pstewart at nexicomgroup.net> Paul, PS> Could someone please explain the "bit flips" ? Sorry, I PS> haven't taken any time to understand this .. is it just a PS> matter of the correct rsync command switches? PS> In our rsync crontab we have: PS> # CENTOS Mirror 01 * * * * www-data /usr/bin/rsync -rtlzv PS> --delete rsync://mirror.steadfast.net/centos/ /var/centos/ You should be using the -p flag to preserve permissions, which will change the permissions over when they're changed upstream. (We use -vaH ${EXCLUDES} --numeric-ids \ --delay-updates \ --delete --delete-after the -a flag includes -rlptgoD; -H preserves hard links, which is -also desirable.) Some distros (like Fedora) do the staging behind a restricted directory and then ask mirrors to do the bitflip at a particular time by changing the permissions by hand or with a cron or at job, but CentOS appears to be propagating the bitflip through the mirror network instead.
