The disable-services OSCAR package disables the following
services on the client nodes:
- Incoming mail service: the sendmail, exim, and
postfix daemons are disabled. This prevents incoming mail
from being received on the nodes. Note that outgoing mail is not
disabled; most outgoing mail is sent immediately. If there is some
transient failure and the mail is not sent immediately, it will go
to the mail service's queue. A root crontab is installed
that runs every hour to trigger the queue in case this happens.
- Kudzu: the Kudzu service looks for new hardware, usually upon
boot up. At boot time, this process takes over 30 seconds. It is
disabled in order to speed up the booting of individual nodes.
Note that these services are not uninstalled - they are simply
disabled at boot time.
