But doesn't -always- exist on 2.2:

[narvi:/etc/init.d] 11:26:37am 136 % ls -l /proc/sys/kernel/modprobe
ls: /proc/sys/kernel/modprobe: No such file or directory
[narvi:/etc/init.d] 11:26:39am 137 % uname -a
Linux narvi 2.2.16 #6 Fri Jun 23 13:51:08 PDT 2000 i686 unknown

You need to have 'CONFIG_KMOD' set in your kernel build to have it,
which I don't.

Seems to me that the logic on that is broken.  /proc/sys/kernel/modprobe
is not a good way to determine whether kerneld should be run.

Perhaps you should file a bug on it?

It does.  See above.

They run kerneld.  Wrongly.
