"dmesg" should print out error messages, even if /var/log is ro.
If you are lucky enough to get a shell :)
For e.g., how can I redirect syslog to print to another partition? (hoping that partition to stay RW)?just tell syslog where to log: /etc/syslog or /etc/syslog-ng should help here (man syslogd)
Well, I have redirected the syslog to a different partition, and am now waiting for the problem to reccur.
Thanks for your help.
