Hi Damyan.

I agree with you about the coexistence.

Could you chance the names "firebird2-super-server" and 
"firebrid2-2.0-super-server" to "firebird15-super-server" and 
"firebrid20-super-server" because very soon we are going to have FB 2.1, 
2.5, 3.0 and 3.1 according to international news (Dmitry Yemanov in Prague 
November 2006)?

Again, could the directories be "/etc/firebird15" and "/etc/firebird20"?

Could this instalations create the users and groups "firebird15" and

If we change all those information of my questions we can make many firebird 
server versions coexist without problems.

I have no experience on subversion software or building deb files, but I 
learn very fast. Can you teach me the first steps so I can help you with 
firebird and flamerobin deb files?

If we can create firebird and flamerobin deb files, many users can install 
them by dpkg while these deb files are not accepted as "stable" by Debian 
administrators! As a matter of fact, nowadays, I install them on Debian by 
"tar.gz" file...
