cleaning interrupted build "leftovers" ?

cleaning interrupted build "leftovers" ?

[-- Attachment #1: Type: text/plain, Size: 591 bytes --]

  Hello !

  Yesterday, I interrupted (CTRL+C) the installation of
linux-libre@5.8.5 when it was in build phase (substitute not
available yet). Today, a new `guix system reconfigure` has
found a substitute. I am wondering if, in this situation, my system
has "leftovers" from the aborted build, that I would need to
clean… and if so, {where,how} to find it ?! 

  Based on the [attached] result of the following command, I
suppose, but I am unsure.

----
$ sudo find -L /var/guix /gnu/store -name "*linux-libre-5.8.5*" 2> /dev/null
----

  Thanks for your time and best regards,

Fulbert

No, there are no left-overs when aborting a build.
There may be build pre-requisites that are no longer needed, though,
which can be collected by the garbage collector (“guix gc”).

packages are normally built in /tmp, each package in its own subdirctory
guix-build-<package>. When interrupting the build with Ctrl-C, this
directory survives (and on most systems is deleted during the next reboot).

This looks like it is part of your successful upgrade of the system with
a substitute.
$ ls -l /var/guix/profiles
shows links to profiles in /gnu/store (and if space runs out, these can
be removed by deleting profiles and "guix gc").
