The patched source builds and installs flawlessy. However I observed something that seems to be a regression. If I run either xconsole or xterm -C I only see kernel messages, even though my X startup (via XDM) changes the owner of /dev/console to the logged-in user. I mean, if I do some timg like "echo OK > /dev/console", the message is echoed on /dev/ttyv0, not by xconsole This is the same problem reported by Jeff Blank on RELENG_7: http://lists.freebsd.org/pipermail/freebsd-stable/2008-September/044949.html http://lists.freebsd.org/pipermail/freebsd-stable/2008-October/045885.html -- cd /usr/ports/sysutils/life make clean _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
