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

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.

Dear,

This bug report #25638  is about

Well, I am not sure to correctly understand the API of 
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
, I suggest to close this bug.  WDYT?
