Title: [SOVLED] Saving log files ?
Post by: remus on May 28, 2013, 06:25:46 PM

I have remastered microcore boot cd to include syslog bootcode, however If the system reboots, any helpful information that may have been in /var/log/messages is lost.

What is the best way to keep copies of this file that will survive a reboot ?

All comments and suggestions welcome.

Hi remus
You could start syslog in bootlocal instead of using the boot code. This will allow you to specify a persistent directory.
For more info:

Code: [Select]

syslogd --help

Thanks for input Rich,

I've achieved my goals with the following.

Added to /opt/bootlocal.sh

Code: [Select]

sudo syslogd -O /mnt/sda1/messages
sudo klogd
In case anyone else is interested, syslogd can be stopped with
sudo killall syslogd

I'm wondering if klogd and syslogd save output to the same file in microcore/tinycore ?

Yes, busybox klogd passes the kernel messages to syslogd.

Ahh, ok so klogd passes kernel messages to syslogd which in turn writes to the log file, thanks.
