/etc CHANGES: - /etc/drivers.conf has been renamed to /etc/system.conf. Every entry in the file is now marked as "service" rather than driver. - user "service" has been added to password file /etc/passwd. - docs/UPDATING updated accordingly, as well as every other mention to the old drivers.conf in the system. RS CHANGES: - No more distinction between servers and drivers. - RS_START has been renamed to RS_UP and the old legacy RS_UP and RS_UP_COPY dropped. - RS asks PCI to set / remove ACL entries only for services whose ACL properties have been set. This change eliminates unnecessary warnings. - Temporarily minimize the risk of potential races at boot time or when starting a new service. Upcoming changes will eliminate races completely. - General cleanup.
