[06:10] <icey> jamespage: SRU related question - the nfs-ganesha package build disables some features in nfs-ganesha, and it looks like they are just pulled in directly from Debian, I wonder if we would be open to backporting changing a NO to a YES in the package to enable the various RADOS backend bits in nfs-ganesha to Focal+?

[12:54] <jamespage> icey: I don't have any fundamental objection to that
[12:55] <icey> jamespage: I talked to coreycb about it as well, the packaging changes are fairly minimal

[15:16] <linuxr> Hi all, so I try to boot ubuntu 20.04 on a raspi4 from USB, and get the error message "no working controllers found", and then a repeated "ERROR: serverip not set", followed by pxe boot errors..why does it try to boot from pxe? Is this a raspi or an ubuntu issue? thanks
[15:18] <waveform> linuxr, booting from usb on ubuntu is officially supported from groovy (20.10) onwards as focal still uses u-boot which is incompatible with this on the pi. That said, I *think* it's possible with an updated focal image as the later firmwares are capable of unpacking the arm64 kernel, but it would require some surgery of the boot config
[15:19] <linuxr> waveform, do you have some documentation for this?
[15:20] <waveform> linuxr, for modifying the boot config for focal? Not currently but I should sit down and write a post about that
[15:22] <linuxr> waveform, actually I had 20.04 already running, booting from SD card. Trouble now seems to be because booting from USB
[15:24] <waveform> linuxr, yes - 20.04 won't boot from USB without changing the boot config. The TL;DR version would be, ensure linux-firmware-raspi2 is up to date, run sudo flash-kernel, then in /boot/firmware/config.txt: remove all kernel=u-boot* lines, add kernel=vmlinuz to [all] section, remove device_tree_address= line, ensure cmdline=cmdline.txt is in there, ensure root is set correctly in /boot/firmware/cmdline.txt and /etc/fstab and that *should* be it
[15:25] <waveform> (I think)
[15:25] <waveform> I'll see if I can put together a post about it when I've got a mo
[15:27] <linuxr> waveform, that would be great!
[21:06] <waveform> linuxr, here you go: https://waldorf.waveform.org.uk/2021/you-boot-no-u-boot-first.html
[21:07] <linuxr> waveform, oh wow thats so great! Will have a read and try this tomorrow!
[21:20] <linuxr> great article waveform, looks very professional, thanks for the work. Can't wait to see if it works :)
