| |
(For anyone else who shares the opinion that
klogd -f /var/log/kmsg -x
should append to its kmsg log file instead of overwriting it.)
-f insulates klogd messages from syslogd bugs (although you can't split them up into multiple files the way that /etc/syslog.conf enables). You can always solve any klogd-to-syslogd problem *after* you find out what is otherwise wrong with your kernel (and lose the -f switch then if that's what you prefer or require). But when you are debugging a kernel deadlock with no oops, for example, and actually have local persistent storage to write to, it helps if the next hard reset doesn't truncate the -f pathname when klogd opens it.
