Debian package postinst scripts breaks chained replications

As part of the upgrade the postinst script of deb package is starting mysqld instance as followes:
MYSQL_BOOTSTRAP="/usr/sbin/mysqld --bootstrap --user=mysql --disable-log-bin --skip-grant-tables --default-storage-engine=myisam"

You would see that binary logging is disabled, but there is no option: --skip-slave-start
If you have a slave chains setup with the option --log-slave-updates this brief startup during the upgrade process will start the slaves and starts to download and execute binary logs, however because binary-logging is disabled those logs won't be written to disk and thus will not be picked up by other slaves in the chain.
