I tried this one! 😁
The `string-append` version I mean.

`mcron` can then find `notmuch`, but `notmuch` has some hooks that depend
on other commands; `mbsync` and `afew` in my case. For this, I cannot really
provide the full path? 🤔 … actually, I could, but then it would be
`/home/USER/.guix-home/profile/bin/mbsync`, not the actual path.

This should work, but I can help be find it a bit weird, because it
propagates to quite a number of files. 😞
And the same goes for `vdirsyncer` that relies on `pass`…

Oh, actually, I've just figured out that this doesn't actually work,
because my `USER` is not the same on all my computers! 😱
And I cannot rely on `$HOME` because it's not supported by all the
configuration files that are affected.

So I would definitively favour a solution where the PATH is set once and
for all by Mcron.
