[wildfly-dev] Customizing a provisioned server

[Stuart Douglas]

Something I forgot to mention is that these customizations will need to 
be specified per config file, so you may specify different 
customizations for standalone.xml, standalone-full.xml and domain.xml 
for example. Unfortunately this will involve stopping and starting the 
admin only server multiple times, but I can't really see any way around 
that.
