I wanted to install 9legacy as well as 9front (already installed) on
my main PC.
The 9legacy install is the "old" one: I had my CD/DVD drive as the
first SATA device so all hell break loose (because the install insists
on using the first detected 9fat and was trying to write hence the
CDROM 9fat).
So I shuffled my devices to put the MBR partitioned disk first, the
GPT partitioned (with 9front) second and the CD/DVD-RW last.
9legacy is then installed. After verifying that at least kerTeX
installs on it---hence the fix made two days ago---I went back to my
ether8169 duty.
For this, cross reading sources from NetBSD, FreeBSD, Linux and
Realtek, I worked on NetBSD.
The writing done so that it was worth then trying to compile and test, I
went back to 9front...
Well: I _wanted_ to get back to 9front... But 9front has been installed
on what was /dev/sdE2 and is now /dev/sdE1.
I modified my plan9.ini but no! The cwfs64 has its config, that says
"/dev/sdE2" and I loop back to bootargs prompting.
Having read that the device was identified in the NVRAM, I dd'ed the
NVRAM blocks for inspection. Nothing except the record for Glenda. To
play it safe, I zeroed the NVRAM. Same result. It's not there.
The paper says that the config is stored in the first block of the
device. It is unlikely to be in the MBR (if every OS would use it
for its own stuff, it would be a mess). It's not, for the same
reason, in the first block of the "primary" partition of Plan9. It's
not in the second block holding the plan9 proper partitioning.
So where is the config? First block of "fscache"? of WORM? of "other"?
Elsewhere?
I can put "-c" in bootargs to get to fsconfig. But what is the syntax
in order to not wreak havoc? The man page gives SCSI syntax, but what
about SATA sd drives?
Can I give "-m /dev/sdE1/fscache" in bootargs that would magically
fix the config?
Is there a way to specify to the file service "hic": "handle the device
you sit on", so that it is relative, "movable"---dd'ing the whole Plan9
partition elsewhere will work?
TIA for tips, explanations and magic invocations!
