Instead of full GNU diff (which smaller boot environments may not have), use "comm" which is more available.
Although using "comm" requires CONFIG_PRINTK_TIME=y doesn't it?
No, it doesn't seem to. "comm" doesn't carry about the line prefixes. AIUI, the only reason for a mention of "sort" is because of how "comm" does its line pairing. i.e. as soon as it goes out of sync, it starts accounting for the disjunction between files. But that's exactly what we want it doing, and the prefix doesn't matter.
OK, if it works.
