Description Paul Iadonisi 1999-07-27 17:26:05 UTC
I've created an rpm for VMware that stops the vmware
processes before uninstalling (the %preun script) and starts
the processes after installing (the %post script):


# Make VMware start/shutdown automatically when the machine
does it.
/sbin/chkconfig --add vmware

# Restart in the same way that vmware will be started
/etc/rc.d/init.d/vmware start

/etc/rc.d/init.d/vmware stop
# Remove autostart of vmware
if test $1 = 0
   /sbin/chkconfig --del vmware
An upgrade of this package, with no changes to either the
%post or %preun scripts, should presumably stop the vmware
process, delete it from chkconfig control and then upgrade
the package, add it to chkconfig control, and start the
vmware processes.  What happens instead is that the rpm is
upgraded first, and then the processes are started (%post
script) and lastly, the processes are stopped (%preun
script).  This looks like the wrong order, to me.

Comment 1 Paul Iadonisi 1999-07-27 17:27:59 UTC
The version of rpm is rpm-3.0.2-6.0

Comment 2 Jeff Johnson 1999-07-27 20:19:59 UTC
Rpm always installs (and runs %post) before uninstalling (and runs

Rewrite your %preun as follows:

# Remove autostart of vmware
if test $1 = 0
   /etc/rc.d/init.d/vmware stop
   /sbin/chkconfig --del vmware
