Actually, even what depends on it. That's the whole thing the
rebootstrap script I mentioned is about, and it's making progress, it should be able to produce essentially what is needed to run debootstrap/crosshurd.

Ah, I don't mean the troubles due to cross-compiling specifically (I
don't think the Hurd libraries are any more problematic compared to
the usual cross-compiling issues?), but simply the fact that they
FTBFS on x86_64-gnu unless you apply my changes -- that only exist on
my machine, for now. And there are a lot of them, mostly strategically changing size_t to mach_msg_type_number_t in many places, but there
are subtler ones too.

Ok, I'll just apply the patches :)

FI, I'm having debian hurd-amd64 packages cross-built, I'm getting e.g.
dash built, I'll probably have rumpkernel built too. Essentially, we
should be able to debootstrap a whole chroot.

Awesome!

Are these (binaries? debs?) available for download somewhere? Having
rumpdisk would be very helpful if I don't manage to get ramdisk
working.

When I'll get them I'll make a repo, yes, but hopefully hurd-amd64 will
get opened on debian-ports soon so I can just put them there.

Ramdisk should be easy to get working :)

But yes, rumpdisk and lwip will be very convenient to have.

I have put what I already have on https://people.debian.org/~sthibault/tmp/hurd-amd64/

Quick update, I'm already running ramdisk (with glibc and Hurd built
locally, not with these packages) and diskfs spawns a second thread
which starts running (yay!), but it's getting self = NULL in
entry_point (htl/pt-create.c) since
sysdeps/mach/hurd/x86/htl/pt-setup.c doesn't pass the function arg for
x86_64 correctly. So that's where I'm at currently.

Luca, please try reproducing (and fixing) the two issues I reported
here earlier:
* fs/gs base not being set when context-switching to a thread via
thread_invoke / call_continuation
* somehow returning to userspace (and then crashing) after calling task_terminate (mach_task_self ())

Wow! Thanks a lot for your continuous effort!

I'll try to build a ramdisk with these packages and see where we get
(not far I suppose, mainly because of the issues introduced by my last
fs/gs base patch... :( ).
