We have :
/etc/init.d/postfix
# Provides:          postfix mail-transport-agent

/etc/init.d/fetchmail
# Required-Start:    $network $local_fs $remote_fs $syslog $mail-transport-agent

but fetchmail starts before postfix.
In /etc/init.d/.depend.start fetchmail is also before postfix.

Only a "Required-Start: postfix" will make postfix to start before fetchmail.

Yes, postfix fail to provide the virtual facility
$mail-transport-agent.  Why do you report this as a bug against
sysv-rc?  It is a bug against postfix.

See <URL: http://wiki.debian.org/LSBInitScripts/DebianVirtualFacilities >
for more info on virtual facilities
