Subject: [PATCH] common/rc: print out kernel version too
Date: Wed, 10 Jul 2019 14:58:09 -0300	[thread overview]
Message-ID: <20190710175809.13391-1-mfo@canonical.com> (raw)

The kernel version (uname -v) may also be needed in addition to
the kernel release (uname -r) in order to properly identify and
distinguish different kernel builds in some cases/distributions.

For example, in the Ubuntu kernel package the test/debug string
is usually a suffix to the version field, not the release field.

  $ uname -rv
  4.15.0-51-generic #55-Ubuntu SMP Wed May 15 14:27:21 UTC 2019

  $ uname -rv
  4.15.0-51-generic #55+test20190520b1 SMP Mon May 20 11:57:40 -03 2019

Looking at other OSes uname(1) man pages it looks like '-v' is
quite standard, and the Linux man page only cites '-p' and '-i'
as non-portable, so the change should be OK. The only caller is
the 'check' script for the header print out, so it's contained.
