Subject: [PATCH] kbuild: use hostname -s along uname to obtain LINUX_COMPILE_HOST
Date: Wed, 30 Mar 2022 20:23:29 +0200	[thread overview]
Message-ID: <20220330182329.52310-1-s23265@iisve.it> (raw)

From: Francesco Duca <s23265@iisve.it>

* On some systems (e.g. macOS), using commands like 'uname -n' or
  'hostname' will print something similar to "hostname.domain"
  ("Francescos-Air.fritz.box" for example), which is very annoying.
  What works instead is 'hostname -s', which will only write hostname
  without the domain ("Francescos-Air" for example),
  but also keep 'uname -n', as some systems as Arch Linux does not have
  'hostname' as command.

* This commit is complementary to
  1e66d50ad3a1dbf0169b14d502be59a4b1213149
  ("kbuild: Use uname for LINUX_COMPILE_HOST detection")
