Recent changes: ^^^^^^^^^^^^^^^ +20050417: + postinstall(8) was moved from /etc to /usr/sbin and made part + of the "base" set, to make it easier to invoke after an + upgrade. + +20050211: + Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in + some of the cross tools to fail if they use configure. Some configure's + cache the environment passed in and notice the new environment is + different and abort. Doing a clean in tools/ should be enough to + make a build continue. + +20050109: + Since su is using pam by default now, make sure that you have + /etc/pam.d populated (postinstall will do that automatically + for you). Otherwise su will fail open (i.e. will not require + a password). + +20041229: + Make had a path resolution bug that manifested itself as not + being able to install openpam.3.

You need to create that device by installing a new + MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]* + +20041006: + + A bug was introduced into /bin/sh (var.c rev 1.35) which causes + variables to not export correctly to subshells in all cases.

Due to the move some Makefile + dependencies are now dangling requiring a make cleandir + before they work again (kdump, ktruss, rescue, ipf, and + ftp-proxy are the victims). + +20040715: + The rc.d/sendmail script now uses a heuristic to determine + if sendmail should be started at boot time. It checks the + contents of /etc/mailer.conf, /etc/mail/submit.cf, and the + owner and mode of the sendmail binary to see if any changes + to the mail infrastructure have been made. If no changes + are detected, it will start an SMTP listener. + + Setting sendmail=NO in /etc/rc.conf will override this. + + If you are only using sendmail by default and only for + local delivery, it is important that you also update your + sendmail.cf so that the SMTP listener only listens on the + loopback interface. + +20040715: + The method by which athhal-elf.o gets pulled into i386 + kernel builds has been changed again.

This affects + consumers of the create and delete interface, as well as + the dynamic discovery mechanism. This is believed only to + be the sysctl(8) binary itself, at this point in time, so + the only effect of this should be that a sysctl binary + built from sources dated between 2003/12/04 and 2004/03/24 + will not work on a kernel built from sources dated after + 2004/04/25.
