Debian/Ubuntu's current /etc/init.d/postfix script does not invoke
master.
That script sets: DAEMON=/usr/sbin/postfix
NOTE: file /usr/sbin/postfix being: /usr/sbin/postfix: ELF 32-bit LSB
shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses
shared libs), for GNU/Linux 2.6.15, stripped
and then uses $DAEMON in start), stop), restart), etc.
start) uses:
awk '/^[0-9a-z]/ && ($5 ~ "[-yY]")' /etc/postfix/master.cf
to check if anything is to be chrooted.
If anything chrooted, the relevant files are copied to the chroot and
after that /usr/sbin/postfix is started as a daemon with:
start-stop-daemon --start --exec ${DAEMON} -- quiet-quick-start
stop)
stop uses: ${DAEMON} quiet-stop
reload)
reload uses: ${DAEMON} quiet-reload

I am attaching the Debian/Ubuntu current /etc/init.d/postfix script:
