If I may be granted the segue, the Postfix documentation has recently
been updated to include the following text:
NOTE: Do not use Gnu TLS. It will spontaneously terminate a process
with exit status code 2, instead of properly reporting problems to
Postfix, so that it can log them to the maillog file.
This was discovered when the Postfix cleanup(8) daemon was reported
exiting in LDAP initialization. The system LDAP library was linked
against GnuTLS, and /dev/urandom was missing from the chroot jail.
The real culprit is libgcrypt, whose log_fatal() macro terminates the
calling process. This is undesirable in a general purpose library. If
the authors of GnuTLS have any influence on the design/implementation
of libgcrypt, I hope they will make an effort to see this issue addressed.
