This would be best done with a sysctl setting. On boot, the values in
/etc/sysctl.conf will be read into /proc/sys/.
The value you want to set is kernel.printk. It's a list of four numbers. From
the kernel doc:
printk:
The four values in printk denote: console_loglevel,
default_message_loglevel, minimum_console_loglevel and
default_console_loglevel respectively.
These values influence printk() behavior when printing or
logging error messages. See 'man 2 syslog' for more info on
the different loglevels.
- console_loglevel: messages with a higher priority than
this will be printed to the console
- default_message_level: messages without an explicit priority
will be printed with this priority
- minimum_console_loglevel: minimum (highest) value to which
console_loglevel can be set
- default_console_loglevel: default value for console_loglevel
Cheers,
Jeremy
