Slight caution... I performed a few updates from 8.0_STABLE (at some point in its history) to 9.0_STABLE and while nearly all packages worked just fine but there were problems with certain packages that linked libcrypto. In particular, sendmail, apache and postgresql would drop core when they attempted to use crypto functions, for example, postgres would not be able to take connections that were gssapi based, but normal ones worked fine and sendmail would be unable to start at all. I do not fully understand what was happening except that it seemed like the main body of the program would get the newer libcrypto, and then would dlopen (in the case of apache, for example) a .so. module which was hard linked to the older version and things went south from there. Not all packages were effected, for example, samba4 was just fine. This would have been between libcrypto.so.12.0 and libcrypto.so.14.0. This condition for me was 100% reproducable (for amd64 at least) and happend on a number of systems I updated using the "overlay the new stuff followed by postinstall" method that I always use. -- Brad Spencer - b...@anduin.eldar.org - KC8VKS - http://anduin.eldar.org
