[DNG] buster to beowulf
I'd like to pretend to be a former Debian user who wants to try out Devuan, and perform the cross-grade as a former Debian user might. The point of course, is for find out if there are any glitches before beowulf goes stable. I'll be doing it on a real hardware computer, not a VM. I have found the instructions to migrate jessie to ascii. Is there a draft of the instructions from buster to beowulf? A draft I could maybe help debug by following it? -- hendrik ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
[DNG] PXE booting, initial notes
I want to be able to install via PXE booting, but Devuan doesn't (yet) provide the tools for this. So, I've started poking around, and I've got something crufted together. There's more work to do, but I wanted to share what I've got now. Maybe it'll inspire someone and they'll cross the finish line sooner than me. I stared with netboot.tar.gz from Debian and a Devuan netboot ISO. My DHCP server is Debian 9 right now, but this shouldn't matter much. I added this extra bit of configuration, global scope in /etc/dhcp/dhcpd.conf. allow booting; next-server 1.2.3.4; filename "pxelinux.0"; Change 1.2.3.4 to the name or address of your DHCP/tftp server. I then installed tftpd. Something that ends up being useful is adding the -s flag to inetd.conf and restarting inetd, so that we don't have to edit all the files we'll pull from the ISO. So, at the end of the appropriate line: /usr/sbin/in.tftpd -s /srv/tftp The Debian netboot stuff is all relative paths, whereas the ISO looks for /linux and /initrd.gz. The -s flag is fine for either Devuan or Debian. We want pxelinux.0 from Debian's netboot.tar.gz until I learn how to build it locally, so: cd /srv/tftp ; tar xf /path/to/debian/netboot.tar.gz rm ldlinux.c32 pxelinux.0 pxelinux.cfg version.info cp debian-installer/amd64/pxelinux.0 . rm -r debian-installer (In short, we pulled out that one file, and nuked everything else.) The rest of the bits come from the Devuan ISO: mount -o loop devuan_ascii_2.1_amd64_netinst.iso /mnt cp /mnt/isolinux/* . cp /mnt/linux . cp /mnt/initrd.gz . cp -r /mnt/install . mkdir pxelinux.cfg ln -s ../isolinux.cfg pxelinux.cfg/default Note that you can't actually install from this yet, as what we boot is quite literally the netinst CD's contents, and it wants to find an attahed CD, but this is an initial set of notes, so we'll push on. Next for me: I want to net-install Beowulf ZFS installs, based on my physical media installs, so I'll write up notes about how to use debootstrap to build an install environment we can netboot, presumably with an NFS root. We should be able to identify the config bits that want a CD and swap in config bits that just default to wanting a network mirror. If you take their netboot.tar.gz initrd and unpack it: gzip -cd initrd.gz | cpio -id in a directory somewhere, pay attention to, among other things: sbin/debian-installer* lib/debian-installer* We presumably have all the tools we need, and just need to point debconf/d-i in the right direction. -- Mason Loring Bliss (( If I have not seen as far as others, it is because ma...@blisses.org )) giants were standing on my shoulders. - Hal Abelson signature.asc Description: PGP signature ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

This is stolen from the forums and modified slightly. Most of the wording is taken directly from the post, but I've added details so I can find everything in one spot.

A draft > I could maybe help debug by following it? Yes, I have been working on this. Attached is the script I have been testing. It single steps through. I don't propose we publish the script but it makes testing quicker. Or just run the commands manually. It requires 2 passes.
