\o/ thanks!

My understanding was that this silenced a scary but harmless 
warning from older (GNU?) tar versions.  I'm happy to see it go if 
it actually breaks others.

Both Alpine compatibility changes are very welcome but should be 
in a separate commit.  Keep commits confined to one logical change 
whenever possible.

OK.  I didn't realise the script still had severe bashism.

Add a ‘return 0’ line here for consistency with the rest of the 
code.

[[:digit:]] wasn't strictly required here, right?  I understand 
that it's more ‘correct’ but can't imagine any locale actually 
breaking either one.

Is there a practical chance that some ancient-but-supported grep 
out there supports [0-9] but *not* [[:digit:]]?

If not: OK!

I'll defer to your expertise on the OpenRC incantations :-)

Minor nitpick: ‘; }’.

I like the subdirectory.

Please rename this to guix-daemon.in & add it to nix/local.mk so 
we can use @localstatedir@ here.

If you could send a revised patch series it would be much 
appreciated; otherwise I'll make the above changes when I get 
around to it (...).

Thanks!
