Re: Installation manual updates -- done

Hi Jurij,

Thanks a lot for taking the time to go through the whole manual.
I've gone through the issues and fixed a number of them; quite a few had 
already been fixed by changes since your review.

There are also a few issues in this mail that are not yet fixed, but that 
could be fixed really easily if I can get the correct info or a second 

I'll follow up with issues that are still open in a separate mail.

Done based on your patch.

Not sure. It kind of covers the fact that the statement be not be true for 
the arch for which the manual is being read. We could remove it if we had 
a "supports-cd" condition, which we currently don't.

It probably makes more sense to just replace it with a generic statement 
that says "all SCSI devices supported by the kernel are supported", and 
maybe list any SUN specific devices (as I've done for networking in 
current version on alioth [1]).

Can you suggest something quickly?

Already removed.

Will test that tomorrow. 32 may still work actually. I'm not sure if I 
tested that for Sparc when I last did my lowmem tests.

Done, or at least changed. Could you check if any Sparc specific info is 
missing? Or maybe that should just be dropped?

See comment above. Inconsistency well spotted, will update.

Google gave me this link; updated. Is that correct?

Cleaned out old cruft. The para is now no longer printed for Sparc.

Section was partially updated recently and better explains how to check 
for location used.
For tftpd-hpa (which is recommended), the default is /var/lib/tftpboot. 
What do you use?

For me it is 0A134205. I think this is adequately explained I've added a 
suggestion to check the log.

'boot net' works for me too. However, this para only suggests how to 
_force_ the image name, not what the regular command is.
I have added this in the new text.

What does 'boot net-tpe' different from 'boot net'?

Both done.

This is listed in errata. removed here.

Should go in "Troubleshooting section in this chapter. But I guess we've 
already covered that.

Both already done.

Already done; see current 5.3.4. A check could be useful.

Hmm. Don't see anything like that. Is probably already gone.
