Is it possible to add a custom root certificate into the Thunderbird
3.0 installation directory so that it is available for all users and
they don't have to import it manually? I see that the default root
certificates are built into the library libnsscki.so. Hacking that
library or overwriting cert8.db at installtion isn't a clean solution.

We run Thunderbird on Linux from a central NFS mounted application
directory and use the autoconfig feature to setup a dummy proof
Thunderbird for our users.

Thanks in advance,
