[PATCH] modify ver_linux to check e2fsprogs and more.

[Steven Cole <elenstev@mesatop.com>]

[-- Attachment #1: Type: text/plain, Size: 5298 bytes --]

I have modified the scripts/ver_linux script to provide the following:

1) The order of version checks is now the same as the list in the
   Current Minimal Requirements section of Documentation/Changes
   for easier comparison.
2) Made capitalization  consistent with the list in Changes.
3) Added version check for ext2 utils (e2fsprogs).
4) Added version check for pcmcia utils (pcmcia-cs).
5) Added version check for pppd (PPP).
6) Added version check for isdn utils (isdn4k-utils).
7) Added whitespace for better readability.

Due to the extensive rewriting, the patch against 2.4.1-ac6 is
larger than the ver_linux script itself.  I will include the proposed
new version of ver_linux here inline, and I will attach the patch itself,
which isn't as readable. This patch should apply against -ac5 and -ac7 also.

Here is the output of the current ver_linux for my system:

[root@localhost scripts]# ./ver_linux.orig

-- unusual then possibly you have very old versions)

Here is the output of the new ver_linux:

[root@localhost scripts]# ./ver_linux
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

This output can be compared with the list in Documentation/Changes:

Here is the proposed new version of ver_linux, patch against 2.4.1-ac6 attached.
