And yes, on all the machines with no serial I do installation over ssh, too. Also great is netbooting - learned that installation method years ago as "jumpstart" in solaris an use it whenever possible. It's amazing how flawless that concept works on small ARM SoC with uboot over serial lines. > In any case, thank you for the great work and I wanted to simply let > you know that sparc64 seems to work fine for the basic stuff anyone > would want. Thanks from my side too and hoping for an opportunity (time!) to try on the old sun iron still beeing in our basement.

I may have mentioned in the past that I *always* use the expert mode text installer to get the job done. Mostly because I can walk away from the machine and run the bulk of the installation process remote over a ssh connection. That is the greatest feature in the installer ever! Certainly top of the top ten features in an otherwise slick and easy installer process. I assure you that Red Hat could learn a lot. I hate their graphical garbage installer. The other great feature of the expert mode is that I can set the ip address and not get locked into DHCP. I do have a very small DHCP subnet but that is only to deal with a few windows clients. Otherwise all hosts fall into a subnet 172.16.35.1/26 which is for lab systems. It does just work great and I even have ppc64 and ppp64le running fine. I don't do anything graphical on those hosts other than some X11 work. The sparc64 installer from 2020-10-13 works great and the only snag I hit was self inflicted with the gpt label. I knew when I did it that it was a mistake but plowed ahead anyways. I do wish there was a way to get an M3000 or even better an M4000 running as those things have actual horse power for real world work. The XSCF is not a big deal to manage on those but I suspect the firmware is the real problem once one gets a console to a hardware domain. I don't know. I have not tried on those machines in years and would like to get my M4000 up and running just to see what happens. In any case, thank you for the great work and I wanted to simply let you know that sparc64 seems to work fine for the basic stuff anyone would want. -- Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spoken GreyBeard and suspenders optional

Just a guess. Let me know if this seems reasonable. Yes, GPT is supported on SPARC T4 and newer only. Normally, when you use automatic partioning, the installer should detect whether your machine supports GPT and if not, use a Sun-based partition layout. Adrian -- .''`.

Unrecognized magic number in media label
I was just testing the installer image at : https://cdimage.debian.org/cdimage/ports/snapshots/2020-10-13/ Everything seems to just work fine. Until reboot wherein I see : Boot device: /pci@1f,0/pci@1,1/scsi@2/disk@0,0:a File and args: Unrecognized magic number in media label Can't open disk label package Evaluating: boot Can't open boot device ok I am guessing that my mistake was to use a gpt label on the boot disk and the old firmware on this test Netra machine can only grok a sun label. Just a guess. Let me know if this seems reasonable. -- Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spoken GreyBeard and suspenders optional
