Ok, problem solved (in a dirty way)
First things first...
The segfault came from the following line in genkd:
# PARTDEV=`echo $KDDEV | tr -d [1-8]`
tr did not trim /dev/hda1 into /dev/hda.
So far this segfault will not disable genkd because it continued to
work as expected.
However....
when reaching for the sfdisk part:
Note: $PARTDEV value is /dev/hda
# if `echo ";" | sfdisk $PARTDEV /dev/null 2> /dev/null
sfdisk did nothing, in fact running it manually gives:
"seek error; wanted 0x0000000000000000, got 0x0000000000000000"
Obviously if it does not create the partition correctly the script will die.
sfdisk -g /dev/hda output
/dev/hda: 77520 cyl, 16 heads, 63 sec/track
Solution:
a- use fdisk to create the 40 gig partition (/dev/hda1)
b- use "mke2fs -L ASTKD /dev/hda1"
c- ran "genkd /dev/hda" as it will now work due to reutilization of
existing partition (no sfdisk involved)
after all this i ran "sfdisk -l" to list the partitions and this was the output:
# sfdisk -l /dev/hda
"seek error; wanted 0x0000000000000000, got 0x0000000000000000"
"no partitions found"
So it seems that sfdisk does not play along with my WesternDigital 2.5
inch hard disk.
I googled a lot and found no reference of a sfdisk limitation due to
disk geometry, however I must say that my USB key (1 gig) and my CF
card (256meg) were perfectly written by genkd (genkd /dev/hdc and
genkd /dev/sda).
So I'm thinking it does have some geometry limitation
Is sfdisk 3.07 990908 (looks like a 1999 year build) the latest available?
As for the root(2,0) part: extract from the root parameter in grub.conf
Command: root device [hdbias]
Set the current root device to the device device, then attempt to
mount it to get the partition size (for passing the partition
descriptor in ES:ESI, used by some chain-loaded boot loaders), the BSD
drive-type (for booting BSD kernels using their native boot format),
and correctly determine the PC partition where a BSD sub-partition is
located. The optional hdbias parameter is a number to tell a BSD
kernel how many BIOS drive numbers are on controllers before the
current one. For example, if there is an IDE disk and a SCSI disk, and
your FreeBSD root partition is on the SCSI disk, then use a `1' for
hdbias.
Hope it help someone.....
