(A copy of this message has also been posted to the following newsgroups: comp.unix.bsd.freebsd.misc) I recently upgraded 3 systems to 2.1.7. One was previously running 2.1.6.1, one was running 2.1.5, and one was running 2.1.0. The following problems showed up after the installation on all three: 1. The installer stomps on /etc/resolv.conf, and doesn't properly resurrect the real one. That meant all three machines were banging on the slow nameserver I happened to use for installation purposes, instead of querying themselves as they were supposed to. Name lookups were slow and caused abysmal performance (especially on the mail server), until I discovered the error. This is definitely a bug; I carefully compared the contents of /etc and /etc/upgrade. 2. The on-screen message erroneously refers to /etc/update instead of /etc/upgrade. 3. Even after fixing /etc/resolv.conf, sendmail performance was abysmal: it took 30 seconds or more between making a connection on port 25 and seeing the sendmail banner. Compiling and installing sendmail from the Allman source fixed it. Something seems to be rotten in the sendmail build in FreeBSD. The following problem only occurred on the machine where I also did a make world to allow for long file names: 4. I don't know if this is a bug, but it feels like one. Make world compiles and installs a new kernel, but both ps and top kept failing with kvm size mismatches until I manually compiled and installed a new kernel after make world. The following problem only occurred only on the machine that started at 2.1.0: 5. Until a second reboot, vi kept complaining about an out-of-date shared library. -- http://www.lightside.net/~fred/ + net access + http://www.lightside.net/ "Attempts to control the use of encryption technology are wrong in principle, unworkable in practice, and damaging to the long term economic value of the information networks." - UK Labour Party
