Dear NetBSD/Alpha:

Would someone be kind enough to answer what I'm sure are some
embarrassingly simple questions, please?

I want to add one extra hard disk to one 3000/400 (which is running
NetBSD/Alpha 1.4.2) and three extra disks to another.  I've followed the
instructions at http://www.netbsd.org/Documentation/misc/#adding-a-disk and
progressed as far as the part in Step 6 which says "vi foo # if you know
what to do." (i.e. the foo generated by "disklabel sd1 > foo")  That's
where I begin to need assistance.

I've appended to this email the lines from dmesg which relate to the the
three disks involved: the existing system disk (an RZ1CF-AF) and the two
extras an RZ26 and another RZ1CF-AF.   I've also included the output from
"disklabel sd1" for the two extras -- I attached the two types to the same
3000/400 in turn to generate this output.  As you'll notice, the RZ26
currently has existing partitions, but I want to delete those and have just
one data partion occupying all of the space on each extra disk.

Could someone show me what foo should look like before I execute the next
step in the process, viz. "disklabel -r R sd1 foo"?

Is this the correct syntax for the next step?

	newfs /rsd1c


Currently /etc/fstab is

/dev/sd0a / ffs rw 1 1
/dev/sd0b none swap sw 0 0
/dev/sd0d /usr ffs rw 1 2
/kern /kern kernfs rw

When I add a line for each new file system to /etc/fstab is it important
that the one beginning with "/kern" remains the last one in the file?
Since there'll be only one partition on my extra disks I'll need to add a
line such as

/dev/sd1c /home1 ffs rw 1 2

correct?

Apparently there's no need to edit /etc/disktab?
