file doesn't recognise all "Linux make config build file[s]"

[Ken Sharp]

$ file /boot/config*
/boot/config-2.6.38-16-generic: Linux make config build file
/boot/config-2.6.38-8-generic: Linux make config build file
/boot/config-3.2.0-30-generic: ASCII text
/boot/config-3.2.0-31-generic: ASCII text

/boot/config-3.2.0-30-generic: text/plain; charset=us-ascii
/boot/config-3.2.0-31-generic: text/plain; charset=us-ascii

The files are practically identical.

Then again looking at

28 string make\ config Linux make config build file

it looks like these files might be incorrectly recognised as make config files.

[Ken Sharp (kennybobs)]

Doesn't recognise any of the newer config files.

I see what the issue is now, will submit a patch upstream later.

[Ken Sharp (kennybobs)]

This should appear in File 5.18 (Utopic). I don't have the options to set this in Launchpad.

[Ken Sharp (kennybobs)]

$ file -i /boot/config*
/boot/config-4.10.0-38-generic: text/plain; charset=us-ascii
/boot/config-4.4.0-98-generic: text/plain; charset=us-ascii

Format changed again in Xenial.

[Ken Sharp (kennybobs)]

Looking good again in Xenial:

/boot/config-4.13.0-38-generic: Linux make config build file, ASCII text
/boot/config-4.15.0-13-generic: Linux make config build file, ASCII text

But they are newer kernels. I don't have 4.4/10 to check again.

[Ken Sharp (kennybobs)]

Changed again. I guess this will be a never-ending task.
