Subject: Remove zfs service only on uninstall, not on upgrade
X-Git-Url: https://git.camperquake.de/gitweb.cgi?a=commitdiff_plain;h=1fa3bb750d0418dc4a5a3abd2bd8cce9c205c9e1;p=zfs.git

Remove zfs service only on uninstall, not on upgrade

This caused problems on upgrade using RPM:

* The new version will run chkconfig --add, which has no effect
  since the service was already added.

* The old version will run chkconfig --del, which caused zfs
  service removal.

Only run "chkconfig --del" on complete uninstall, by checking
the value of "$1" to %preun, which will be "0" on uninstall,
and "1" on upgrade.
