I have modified #:configure-flags to use `this-package-input', to have proper
cross build support:
--8<---------------cut here---------------start------------->8---
#~(list (format #f "--with-scriptpath=~{~a:~}$PATH"
                (map (lambda (pkg)
                       (in-vicinity pkg "bin"))
                     '#$(list (this-package-input "coreutils-minimal")
                              (this-package-input "sed")))))
--8<---------------cut here---------------end--------------->8---

Thinking of the limitation of %build-inputs, it might be convenient to define
`inputs' and `native-inputs' directly in builder's environment.  🤔

Anyway, applied as f7fc4caf7da8f1d7cc76b3bc6ac0c4e643507454 with above change.

Hi,

I have tried to write a service type for smartd from smartmontools,
however the bundled script fails.

When the test (-m root -M test) is executed, some programs seem to be
missing in the $PATH:

--8<---------------cut here---------------start------------->8---
Jan 14 01:34:19 localhost smartd[3138]: Executing test of <mail> to root ... 
Jan 14 01:34:19 localhost smartd[3138]: Test of <mail> to root produced unexpected output (118 bytes) to STDOUT/STDERR:  
Jan 14 01:34:19 localhost smartd[3138]: /gnu/store/ks6lnp8hssm9zkka47ysa4qp9xd9f8bv-smartmontools-7.4/etc/smartd_warning.sh: line 132: sed: command not found 
Jan 14 01:34:19 localhost smartd[3138]: Test of <mail> to root: failed (32-bit/8-bit exit status: 32512/127) 
--8<---------------cut here---------------end--------------->8---

At the start of the script I see:

--8<---------------cut here---------------start------------->8---
export PATH="/usr/local/bin:/usr/bin:/bin"
--8<---------------cut here---------------end--------------->8---

That does not look correct.  I am not sure if any wrapping is necessary.

Have a nice day,
Tomas
