Bug#767612: jetty8 should not create /var/lib/jetty8/webapps/root on update

[Stephan Wienczny]

Package: jetty8
Version: 8.1.16-3
Severity: important

Dear Maintainer,

when deploying a webapp to root context using "by naming convention", updates
will break your setup. To use this setup you have to remove 
"/var/lib/jetty/webapps/root". This is caused by jetty8s preference for the 
"root" directory instead of "root.war". On update the jetty8 package recreates
"/var/lib/jetty/webapps/root" which causes the "root.war" to be ignored and
rendering your setup broken.
I would suggest packaging to be changed slightly:
1. Move "/var/lib/jetty/webapps/root" to "/usr/lib/jetty8/webapps-root"
2. Create a root.xml in "/etc/jetty8/contexts" which configures a root context 
   to "/usr/lib/jetty8/webapps-root"
This way a configured root context will not be broken by updates. Deploying 
them requires slightly more configuration.
