Subject: scripts/ver_linux lossage on Fedora 11

I found a few places where ver_linux fails to DTRT on Fedora 11

1) mount version
mount --version | awk '{print $NF}' | sed -e s/^mount-// -e s/\)$//

Unfortunately, Fedora's mount command says:

% mount --version
mount from util-linux-ng 2.14.2 (with libblkid and selinux support)

2) nsf-utils

showmount --version 2>&1 | grep nfs-utils | awk \
'NR==1{print "nfs-utils             ", $NF}'

% showmount --version
showmount for 1.1.5
% rpm -q nfs-utils
nfs-utils-1.1.5-6.fc11.x86_64

3) udev

udevinfo -V 2>&1 | grep version | awk '{print "udev                  ", $3}

% udevinfo -V
the program '/bin/bash' called 'udevinfo', it should use 'udevadm info <options>', this will stop working in a future release
141
% udevadm --version
141

Patch for 2 of these attached.  The showmount one may best be fixed by getting
the --version output fixed to include 'nfs-utils' - or do people think
changing it to another egrep [0-9] is the proper approach? If so, I'll do up
an updated patch...
