Dear community
I have copied the 'install75.img' to a USB stick, booted from it and
chosen the "(I)nstall" option. My intention is to install the
distribution sets from the stick, and not via http, because I'd like to
install OpenBSD on our 4 home office PCs without downloading the sets 4
well...OpenBSD is small, and bandwidth is cheap/free. But yeah, I was
"recycling" back when it was called being "a cheap bastard", I get it.
Escaping to a shell and entering 'sysctl hw.disknames' shows: 'sd0, sd1,
sd2, rd0'. 'sdX' are the 3 internal SSDs. Am I right in assuming that
'rd0' is the USB stick?
as you have discovered...no.
Installation step "Let's install the sets!":
I have chosen the option to install from a local disk partition, and
answered with "partition not mounted".
correct.
Issue:
The installer shows 'sd0 sd1 sd2' as available disks, but not the USB
stick 'rd0'.
also correct. Besides, rd0 is mounted. But it is also wrong.
Question:
What do I have to do to make the USB installation stick available for
accessing the distribution sets? Concerning 'install75.img', the
"Installation notes" say: "An install or upgrade can be done with a
USB key without network connectivity."
But how?
dmesg|grep sd
will show you what all the devices are, pick your USB drive. It will guess
correctly after that.
Installing the sets via http works without any issues, but that's not
my plan for the remaining and future installations.
But here's an easier way, if you understand a bit of what is going on.
The system booted from bsd.rd, and it has utilities in "rd0". At this
point, it is NOT ACTUALLY USING the USB drive. So...you can now unplug
and plug it back in...and you will get some white on blue text telling
you what device was unplugged and what was plugged in.
Of course, you don't really want to do that if you don't know for
sure that the drive is unused, but if things are as you describe it,
it's safe.
But most likely, it's sd2, because USB devices are enumerated AFTER
IDE/SATA/SCSI/SAS/RAID connected drives. (but there are things that
can happen that keep me saying, "most likely" and "here's how you
find out" rather than just assuming sd2. :) )
