I have a better suggestion. How about we make write(2) on /dev/console to act as printk()? IOW, how about making _all_ writes to console show up in dmesg?
Then we don't need anything special to do logging _and_ we get output of init scripts captured. For free. dmesg(8) would pick that up, klogd(8) will work as is, etc.
Linus?
