11716	postfix will need a patch or sed for linux-5.0.	ken@…	Bruce Dubbs	"The 5.0.0 kernel is possibly going to be released in a few hours, or alternatively in a week's time.  Too late for our 8.4.

Testing a build in chroot while running on a 5.0.0-rc host kernel, postfix failed,

{{{
ATTENTION:
ATTENTION: Unknown system type: Linux 5.0.0-rc4
ATTENTION:
}}}

If it recognizes the system as Linux 3 or greater, it displays it as LINUX.

At first I thought this was similar to March 2015 when 4.0 was released, but upstream has made an extra change. Details in debian #922477. I adapted the patch suggested by Sven Joachen - rather than care about Linux-6.0 and later, for Linux-5, as well as Linux-4 use a RELEASE_MAJOR of 3 (4.xx is treated like 3.xx, the RELEASE_MAJOR setting in a separate file unnecessarily complicates things.

As of 13 hours ago,neither the development version of postfix, 3.5-20190221, nor the pre-release of 3.4, were adapted for Linux > 4.

Following sed seems to work:

{{{
sed -i -e 's/\$RELEASE_MAJOR/3/' \
       -e '/Linux..3/s/34/345/' makedefs
}}}
