bug#34402: Inferior channel (I believe 'inferior-for-channels' function specifically) sometimes fails |

I got the error again, I've attached the output.
It looks like line 16205 (at the bottom pretty much) shows that a permissions
issue is the culprit:
openat(AT_FDCWD,
"/home/itsme/.cache/guix/checkouts/pjmkglp4t7znuugeurpurzikxq3tnlaywmisyr27shj7apsnalwq/.git/FETCH_HEAD",
O_WRONLY|O_CREAT|O_TRUNC|O_CLOEXEC, 0666) = -1 EACCES (Permission denied)
That file, along with is owned by root and is in the root group, and
permissions are set to `-rw-r--r--`.
It looks like this is caused by me running a guix command as root, with `sudo
-E` (the -E is probably why it's modifying ownership of files in my user's guix
cache directory), that checks out the git commit (I assume since it's only
changing the ownership on those two files, the rest in that directory are owned
by my user).
Changing the owner of that file back to my user has made the error go away when
running `guix package -n -m example-manifest.scm` - and if i then run that
command again with 'sudo -E', the ownership of those files is changed back to
root.
