Fedora 18 changes the way how to work with services in spec files. It introduces new macros - %systemd_post, %systemd_preun and %systemd_postun; which replace scriptlets from Fedora 17 and older (see https://fedoraproject.org/wiki/Packaging:ScriptletSnippets#Systemd, https://bugzilla.redhat.com/show_bug.cgi?id=850016).
Package tomcat6 has been deprecated in Fedora 19 and later. I am closing this bug as WONTFIX. For more information why tomcat6 was deprecated see: http://bugzilla.redhat.com/918010 http://lists.fedoraproject.org/pipermail/devel/2013-March/179847.html http://fedorahosted.org/fesco/ticket/1094
The scriptlets for f18 are as shown at https://fedoraproject.org/wiki/Packaging:ScriptletSnippets#Systemd. changing state to CURRENTRELEASE.
