AFAIU, what Alex told me, on Posix installer creates user "firebird" and
group "firebird". User "firebird" own any objects which is created and used by
Firebird (/tmp/firebird folder, memory mapped files, databases, etc). To work
with Firebird embedded, users must be member of group "firebird".

You can ask for more exact explanations in fb-devel.

Lock table and few other files are placed in /tmp/firebird only, it not depends
on any environment variable.

Hope this helps,
