Hmm,

in this specific case (libnns-ldap failing due to missing
/dev/(u)random devices in early boot when connecting to the ldap
server using a ssl protected session.) the only thing actually using
gcrypt directly is gnutls.

Should gnutls have setup an error handler using
gcry_set_fatalerror_handler?
