Small and bootable

[Seb Tennant <sebyte@smolny.plus.com>]

Hi all.

I've read that it is a good idea for the 'root' partition to be small 
and bootable, i.e., for it to only include /bin, /dev, /etc, /lib, 
/mnt, /root and /sbin.   Presumably, as these directories contain 
predominantly static files, there is very little chance of a 'root' 
partition organised this way ever becoming corrupted and therefore it 
is far less likely that you are ever unable to boot into your system, 
despite what happens elsewhere.

Regardless of how many partitions accommodate the rest of the 
filesystem, (/usr, /tmp, /var e.t.c.), is this a fair assertion?
