Replying to myself,

According to an old thread 
(http://lists.andrew.cmu.edu/pipermail/info-cyrus/2007-September/026772.html), 
the file format is:

USER "$username"
USER "$username2"

It is also confirmed that the only way to have singleinstancestore 
preserved is to run the sync_client with the "-f" option so that all 
synchs are done in the same run.

However it seems that the cache which is used to detect the duplicates 
is rather low (UUID cache on the server side: 1000) so that single 
intance deduplication may not be very efficient.

Unless this has changed, I agree that the best way to initialize the 
replica is to use rsync and then convert the databases. I'll give it a try.

Regards,
Thibault
