Bug#532286: tomcat6: de facto conflicts with tomcat5.5 when insserv is used

[Marcus Better]

Package: tomcat6
Version: 6.0.18-3
Severity: important

The init script has a "provides: tomcat", just like the tomcat5.5
package. Hence the packages cannot be installed together:

~$ sudo aptitude install tomcat5.5

tomcat6 should either provide the "tomcat6" service or conflict with
tomcat5.5.
