I've spent some time trying to port plan9port (aka Plan 9 from User Space) to the #Hurd yesterday. It's not quite working yet, but many subprojects already build, and at least mk works.
The really exciting part of course would be to switch the custom filesystems back from 9P over a Unix socket to real Hurd translators.
And here's a pull request: https://github.com/9fans/plan9port/pull/259
@bugaevc I'm curious, do translators work over the network like 9P does? What do they offer that 9P doesn't?
@grainloom yes and no. The translators work over Mach IPC, which is itself not network-transparent, but it can be made to be using a pair of special proxy tasks, a lot like Unix pipes are not network transparent, but there's netcat that makes them n.t.
Conceptually the translator API is similar to 9P, but translators are capability-based & do a lot more than 9P servers, e.g. translators handle UIDs/GIDs/auth, exec'ing using the exec server, etc.
It should be possible to build a 9P translator.
@bugaevc Fantastic! 👏🏻
wow that is really, really awesome! great work!
"del snarf I look"

"del snarf I look"
@bugaevc *looks up with extreme interest*
what's going on here please explain
@cwebber I don't know how familiar you are with all this, but basically,
• Plan 9 is an OS, the next project of the Unix team at Bell Labs after Unix; like Unix but better, simpler and with native network transparency
• plan9port aka Plan 9 from User Space is a port of Plan 9 userspace programs/utilities to run under Unix
• GNU Hurd is a Unix kernel based on microkernel architecture that can be used instead of Linux
• now it is possible to run plan9port on top of GNU/Hurd Unix systems too
@bugaevc plan9port on gnu hurd on gnu guix when
@cwebber if Guix supports Hurd, then as soon as i upstream the Hurd port 😉
(and add GNUstep to the stack!)
How can I get started running it?
@selea or do you mean Plan 9 / the Hurd in general?
@bugaevc Neat !
20 years passed since the last time I booted HURD, but let me say this is a great job.
Btw. is there any active developement on HURD these days?
Is it still on Mach or did they finally port to L4?
@Wolf480pl not active, but it doesn't seem stalled either
Of course it's still on Mach, why does everyone think they were actually going to move to L4? There were discussions and even prototypes, but nothing serious came out if it, as far as I'm aware.
I was under the impression that Mach's performance issues were a blocker, but maybe I was wrong.
@Wolf480pl it wasn't a blocker per se; Mach works fine if somewhat slow
@bugaevc I'd have more faith in something seL4 or Fiasco.OC, but I may as well be completely wrong.
Anyway, how well does HURD work at the moment? Is it usable as a daily driver?
@SuperFloppies @Wolf480pl just answered about daily driver in the other branch: https://mastodon.technology/@bugaevc/102043156047501428
@bugaevc VERY. CURSED.
@bugaevc Really cool! :D
@bugaevc on real hardware?
@alexshendi of course no, this is in qemu
@bugaevc Plan 9 and Hurd together? That is amazing! Never thought I'd see that.
@bugaevc pretty stuff
