This is a development list - (rpm-list at redhat.com is a user list).

See the arguments to scriptlets which is the package count explained


Guard your test within tests based on $1 - eg

if [ $1 = 0 ]; then
        /sbin/service foo stop > /dev/null 2>&1
        /sbin/chkconfig --del foo

Plenty of examples, you may not want to start in %post automatically
just do chkconfig --add as you might be in the installer (yast,
anaconda) not the real system.  A good sysadmin can do service foo start
or if it is the install env, it'll start automagically on first boot.
