[arch-general] lastsync file on mirrors

is it just me or did the lastsync format change? IIRC the lastsync file was 1 file in the root of the repo, with the date in it in string format. now the lastsync files are like so: <path>/{core,extra,testing,...}/os/{i686,x86_64}/lastsync each containing a unix timestamp. note: no lastsyncfile for any 'any' architecture directory, and also none for either architecture for the community-testing repo. maybe the easiest is to go back to 1 global file, as long as we can make sure somehow that rsync will sync the lastsync file as last thing. I maintain an (official) mirror and would like to monitor these files to prevent out-of-date issues. Dieter
