bug#44519: Qemu fails to start Samba server
Um. Apparently, I was the one failing. I just tried connecting again, and as long as smbd has setuid, the qemu SMB share works as advertised. Sorry for the false alarm.

bug#44520: Graphical installer issues on 1.2.0.
Hey, I cannot reproduce the partitioning issue which is even more frustrating. I guess it was related to the original partitioning of the USB drive I used. Added some more debug logging with 8c287bb2fb1 in the meantime. > Could it be that these get downloaded due to some “debug” output being > pulled (perhaps unnecessarily so but grafting can do that sometimes)?

Oh, right. Thanks for your recent patches on this subject. It should definitely help. Having berlin doing nothing much that serving substitutes and coordinating the build machines will solve many issues. I'm working on that topic and will present my progress during Guix Days! Thanks, Mathieu

Could it be that these get downloaded due to some “debug” output being pulled (perhaps unnecessarily so but grafting can do that sometimes)? > * The substitutes download speed was sometimes super low (~ 50Kb/s). Yes, unfortunately non-offloaded disk image builds (fixed by recent commits) along with GC running all day long has a terrible impact on bandwidth. It should get a bit better at least now that disk image builds will no longer happen on the head node, but OTOH there’s still a lot of build activity happening and that definitely increases pressure. I look forward to the day where using the Build Coordinator we can better decouple the build farm from the node running ‘guix publish’. Thanks, Ludo’.

Also please add this file to ‘EXTRA_DIST’ in Makefile.am.

bug#44053: ‘xdg-mime-database’ profile hook is slow

Interesting, so we should profile that step and see what can be done. I suspect it’s I/O-bound, but maybe we can at least improve feedback. Thanks, Ludo’.
bug#44519: Qemu fails to start Samba server
Hey Guix, Having trouble getting the Samba directory share in qemu to work as advertised: $ qemu-system-x86_64 -netdev user,id=net0,smb=/share ... Running something like the above with samba installed should spin up `smbd`; however, this doesn't happen. I see no smbd processes started. Qemu does create /tmp/qemu-smb.XX/smb.conf, however. Am I just missing something obvious? Can your reproduce? Digging through the qemu repo[0], it looks like qemu calls out to a samba daemon with an invocation that resolves to this: $ smbd -l /tmp/qemu-smb.XX -s /tmp/qemu-smb.XXX/smb.conf Manually running the above results in silent failure, though. To be clear, running the above with --foreground makes no difference. For good measure, I am attaching the smb.conf that qemu generates, in case you want to directly try the smbd command without spinning up qemu. Note, you may need to edit the 'path=/shared' line to an existing directory on your machine. Throwing strace at the above shows that the daemon is getting EPERM when trying to bind() the priviledged ports 445 and 139. Indeed, running the daemon under sudo works as expected, and I am able to access the shared directory from the guest machine as intended. Given the permission issues, I did try adding /sbin/smbd to my setuid-programs, but that seems to make no difference. Is this a PEBKAC issue or a legitimate bug?

If so, the patch I sent yesterday would fix the > problem more thoroughly. Yes it is probably broken too. However, I would prefer not to introduce bootloader specific stuff in (gnu system image). I think the bootloaders should try to do their best with the DEVICE and MOUNT-POINT arguments passed to bootloader-installer procedure. It means, trying to install themselves using only MOUNT-POINT argument or bailing out. WDYT? Thanks, Mathieu
