/proc/kcore size incorrect ?

[J.A. Magallon]

Hi all...

Probably this is a stupid question, but anyways...

I'm trying to make a script to generate an /etc/motd, and I wanted to
include memory size of the box.

I tried:

	echo $(($(stat -c %s /proc/kcore) / 1024 / 1024)) "Mb"

but it gives 1022 for a 1Gb box.

In fact:

	werewolf:~# ll /proc/kcore
	-r--------  1 root root 1072566272 2005.10.23 23:53 /proc/kcore
	werewolf:~# stat -c %s /proc/kcore
	1072566272

	werewolf:~# echo $((1024*1024*1024))
	1073741824

Why that difference ?

TIA

BTW, any simple method to get the real mem of the box ?
