that the linux libre tarballs for version 4.4.18 are no longer
available on any of the usual locations. The next version that has a
full tarball and not just a compressed diff is version “4.4.24-gnu”.

The lack of this tarball doesn’t hurt most users because a substitute
for the tarball is available on hydra, but this doesn’t help when
building everything without substitutes.

Hello!

(Cc’ing linux-libre@fsfla.org. This discussion is about Linux-libre
tarballs that vanish from ftp.gnu.org and fsfla.org:

When building without substitutes, users should end up downloading:

I’ll do that if there are no objections.

That said, if doesn’t seem right if the Linux-libre people remove the
tarball from one directory at ftp.gnu.org and we add it in a different
directory the day after. :-)

What do people think?

If disk space is a problem, I think it would be great if we could agree
on “pinning” specific versions that should never vanish from
ftp.gnu.org. That way we could ensure future reproducibility of
Linux-libre and GuixSD.

Thanks,

bug#25638[Hunting]: linux libre 4.4.18 tarball has disappeared

Dear,

This bug report #25638 http://issues.guix.gnu.org/issue/25638 is about
the linux-libre tarballs for version 4.4.18 are no longer available on
their usual locations.

Currently, such tarballs are not served by
<alpha.gnu.org/gnu/guix/mirror>, if I read correctly.

Well, I am not sure to correctly understand the API of <ci.guix.gnu.org>
in order to see if the tarball is currently on the build farm.

Is such version reachable with "guix time-machine"? I guess no, so does
it make sense to keep the tarball?

Such issue is discussed in #42162, especially the thread starting here:



Therefore, if the linux-libre 4.4.18 tarballs is substituable on
<ci.guix.gnu.org>, I suggest to close this bug. WDYT?


All the best,

It’s available from
now (found a copy at hydra.gnunet.org!). (This URL is served by ‘guix
publish’.) There’s no GC root though.

Good question, maybe not.

Yeah, we can probably close it. The more general issue of tarballs in
general, and linux-libre tarballs in particular, can be dealt with in
the issue above.

Thanks,

Thank you for explaining.
I did not know about hydra.gnunet.org, cool! :-)

Well, Guix could keep all the tarballs until the Tarball Heritage is up. :-)

I am closing. Feel free to reopen if I am making a mistake.
