New Intel NetBSD system running

Hello!
Not that it matters but I've gone ahead and reconfigured one of my systems
to be running NetBSD.

He's currently running version 4.0.1 and I am now building from the most
recent package source blob those utilities and things that are considered
useful by myself and the machines.

I confess that I haven't run NetBSD on Intel since the 1.4 days so it was a
relief to see a working DHCP IP address resolution service here, (of course
replacing the router was a big help) and discovered that the installer was
also gradually re-written.

This was done to facilitate setting up NetBSD to run on a handheld unit.
(HPCARM distribution.)

Installing -current - RZ28 bad sectors

I have been trying to get NetBSD/VAX -current installed on my VS4000/90. 
The install succeeded, but the resulting system would not boot because 
there was a read error on an RZ28.

So, do RZ28 do any kind of bad sector replacement internally? If the 
answer is yes, then the disk is dead. If not how is this handled? I 
don't see to many disk scanning utilities in NetBSD.

It's a normal SCSI drive. SCSI do bad block replacement internally.
It might be worth to try and reformat the drive, but otherwise it's toast.

Depending on where the read error is, it might be possible to use badsect to
avoid using the bad sector.

   Just use scsictl reassign?

   Also, I don't think scsi drives do bad block replacement on reads unless 
they are able to recover the data.  Bad block replacement is controlled 
through one of the scsi mode pages, and could be disabled on the RZ28.  I
don't have one handy to check at the moment, but I'm pretty sure I've got
some around someplace.

   I've used dd to scan disks looking for unreadable blocks, and then used
dd to write the single bad block, which will sometimes cause bad block 
replacement to occur.  If the errors persist, I have used scsi reassing at
times.

Close, but that did not seem to work. I tried to reassign the bad 
blocks, but although it added blocks to the grown defects list, I was 
not able to determine if they were the blocks that asked to be 
reassigned and it also did not stop those blocks from having read 
errors. I settled on scsictl /dev/sd2 format and it seems to have worked 
like a charm. I see no read errors when reading the entire disk now.

Thanks,

slow pkgsrc installs

Now that I have a NetBSD/VAX system running again, I see that installing 
from pkgsrc is VERY slow. It seems to spend most of the time running 
configure and testing the same things over and over again. Is there a 
way to make configure cache its findings? Or can pkgsrc be 
cross-compiled as easily as the base system?

I have to agree. I have not found any problems so far in cross compiling 
and then installing the base -current system. I have begun to install 
packages with no trouble so far.
