Patch up syslogd (which one, actually?) to decode all the dozens of different cases that print out errno values ? Applying your argument more consequently - why do we have human-readable messages at all, instead of just writing out message IDs as hexdumps or binary stream (would make the kernel a lot smaller) ? > but there's not really much need for it to be in the mainline kernel. The idea was having a generic and convenient solution that can be used by other parts of the kernel, too. (just like w/ all the other logging helpers). That's also the reason why I added into vsprintf(). > So when your driver prints "blah: foo bar error 49", > just run a little program that converts 49 to <whatever>. How could that help when userland isn't even up yet ? --mtx -- Enrico, Sohn von Wilfried, a.d.F. Weigelt, metux IT consulting +49-151-27565287
