I believe that this is a good idea, however, I would like to propose a
slightly different approach.
At the moment, it seems that all applications use their own
certificates and maybe also create them upon installation or rather
It may be useful to have a certificate for each service, but it may
also be useful to have one certificate for all services. This may be
discussible but needs to be decided by the local admin anyway. Hence,
we should try to make both ways easily implementable, especially if
the system is to be reviewed or redesigned.
Hence, I propose to stay with virtual per-service certificates, but to
link them to the common snakeoil certificate from ssl-certificates
during configuration and only if there is no other setting.
Dovecot uses </etc/ssl/certs/dovecot.pem>.
This is a symbolic link to </etc/ssl/certs/ssl-cert-snakeoil.pem> if
the above file or link does not exist during configuration of
That way, the admin can easily replace the symlink with a real
certificate if they want per-service certificates.
If, however, they want to have one real certificate for everything,
they can replace the snakeoil certificate like Martin Pitt proposed.
I would like to see some coordination between maintainers of packages
that use or create such certificates. It'll take a while to implement
this anyway, so if only a few packages start and others follow later,
that'd be an improvement anyway.
