Interesting. Looking at ptrace(2), it’s not supposed to fail with EPERM
in the build environment, unless again that’s because of the Yama thing
I mentioned. What’s the value of /proc/sys/kernel/yama/ptrace_scope on
your build machine?
So I’d say: adjust the comment with a link to
<https://issues.guix.gnu.org/48541>, saying that ptrace(2) fails with
EPERM, and push it.
We can always improve later if/when we find more info.
Thanks,
Ludo’.
