Description rbh00 1999-05-03 20:43:58 EDT
My i386 system has two scsi adapters.  Perhaps for this
reason, the contents of my /etc/conf.modules file has
redundant entries.  Here is the file's contents:
	alias scsi_hostadapter aic7xxx
	alias eth0 eepro100
	alias scsi_hostadapter aic7xxx
	alias eth0 eepro100
	alias scsi_hostadapter aic7xxx

Now, mkbootdisk (a shell script) scans this file to set its
variable "ethmodule" at line 80:
	ethmodule=`awk '/^alias eth0/ { print $3 }' \
This results in ethmodule being set to a file with two
lines, that is, to "eepro100\neepro100", and that in turn
causes script /sbin/mkinitrd to cough out its usage message
and fail to do its normal stuff.

(At line 91 witheth is set to "$witheth --with $ethmodule"
and at line 140 $witheth is one of the arguments to

To fix:  Change the "awk" statement at line 80 to eliminate
redundant lines in the conf.modules file:
	ethmodule=`sort /etc/conf.modules | uniq | \
		awk '/^alias eth0/ { print $3 }'`

Note:  This is the stuff of bug 2405 that I tried and failed
to submit to you last Wed Apr 28.  Sorry it took me so long
to regenerate the bug.

Oh and thanks for all your free stuff!

(Later that same day)
A better replacement for line 80 uses the -u option of sort:
	ethmodule=`sort -u /etc/conf.modules |
		awk '/^alias eth0/ { print $3 }'`

I have verified this does occur on a standard 6.0 install.
