doc: add bulk update to primary-script.sh script

This patch updates the script to remark the fact that it should be
used with Linux kernel < 2.6.29. Moreover, it adds a bulk-update
command after the commit in the primary path to avoid any race
condition (the backup may request a resync while this primary
is still committing the entries with an empty internal cache).
This is hackish, but I think that this is the best way to do this
for systems running a Linux kernel < 2.6.29.
