In both cases this is because $test_directory is read-only:

This in turn is due to a permission change in generated tarballs:

That’s an acceptable change IMO, introduced in
68380db4c40a2ee1156349a87254fd7b1f1a52d5. However, the tests were
evidently not run after that change, which is problematic.

Anyway, fixed in 92a0e60a963a54230e400c5c2ae585205489bf35. Both tests
now pass for me.

One issue with 68380db4c40a2ee1156349a87254fd7b1f1a52d5, though, is that
it introduces a copy of the profile being built to the store
(“profile-directory”). This was purposefully avoided before because
it’s very I/O-intensive, space-consuming, and puts more pressure on the
store. It’s a pattern we avoided for system images too, having noticed
its cost (commit 7f75a7ec08975eb6d6e01db61bd6b91f447f655e for instance.)

We may need to come back to a single derivation well or creating packs
for big profiles will be too costly.

Interesting. I had done all my testing using tests/pack.scm (and the
new tests/rpm.scm), and overlooked tests/pack.sh.

I agree it's expensive; we're trading IO for storage though, so the case
of generating the same pack in multiple format, it could be beneficial
by only computing the union directory once. The real motivation was
avoiding code duplication though; perhaps this could be accomplished by
moving the common logic to (guix build pack-utils)?

To be clear, it’s time-consuming and stressful. That’s not sane and I’d
rather not work that way.

Yes, that’s a good idea. There’s already (guix build pack) and I guess
we could move roughly the contents of ‘self-contained-tarball/builder’
and ‘populate-profile-root’ there.

How does that sound?

Thanks,
Ludo’.

Again, thanks for fixing up after me, but you didn't need to put
yourself under such pressure. As the author of the problematic change,
the responsibility of fixing it was on me; I understand this well.

Sounds good. See an implementation in #61949, to which you should be
CC'd already (per 'etc/teams.scm cc-members HEAD^ HEAD').
