So I've started to rsync the italian mirror.
(It takes time tho)
But the content will be available here (158GB to download, almost finished) http://mirror.freelydifferent.com/sabayon/
May be I'll add later a better interface. (But don't really need it in fact)
So, I'll set a cron task to rsync the italian mirror once or twice a day (I guess once is enough right?) I'll do it during the night to insure a better bandwidth.
Or may be twice xD
EDIT: The script for Ubuntu mirror is quite clear. I'm going to use this one and adapt a bit + add some feature may be.
I let you know when I'm done.
The script is working and I set a cron task to update once a day. (If you have any suggestion about the frequency and time, let me know)
I'll try to improve the script and afterward I'll post here or create a new entry into the wiki.
But I'd like to display a kind a summary to be send by mail (Like with the total data transfered, but I don't really now how to get this value tho)
