Sorry to reopen this (I know the feature request doesn't match what I'm now reporting as a bug - if you'd prefer I can create a new ticket).

It looks like the property is overwritten not aggregated.

Steps to reproduce:
# Starting fresh:
{noformat}
wget http://www.apache.org/dyn/closer.cgi/karaf/2.2.4/apache-karaf-2.2.4.tar.gz
tar -xvzf apache-karaf-2.2.4.tar.gz
cd apache-karaf-2.2.4/
{noformat}
# Repeat with/without this next step, webconsole authentication depends on "org.apache.karaf.jaas.boot" being present
{noformat}
echo "org.osgi.framework.bootdelegation = org.bouncycastle.*;" >> etc/custom.properties
{noformat}

# In Karaf shell, install webconsole
{noformat}
./bin/karaf

features:install webconsole
{noformat}
# Attempt to login to webconsole, with the boodelegation in the custom.properties it will fail as it can't find org.apache.karaf.jaas.boot.ProxyLoginModule

>             Project: Karaf
>          Issue Type: Improvement
>    Affects Versions: 2.2.4
>            Reporter: Caspar MacRae
>            Priority: Minor
>
> Hi,
> I tried adding the following to custom.properties:
> {noformat}
> org.osgi.framework.bootdelegation = ${org.osgi.framework.bootdelegation}, org.bouncycastle.*
> {noformat} 
> In the hope that it would do substitution then assignment, but I get an illegal arg exception "recursive variable reference: org.osgi.framework.bootdelegation"  (at org.apache.karaf.main.Main.substVars(Main.java:1201))
> If the above were possible our custom distro would extend rather than overwrite the standard Karaf settings - which would make custom distros a bit more resilient (I'm somewhat fearful I'll miss a change in config, even when running diffs on the stock and custom cfg files).
> (btw creating a custom distro is incredibly easy and a really cool feature, thanks)
