Hi,
pardon me for jumping in ;-), but there is an interesting article regarding file system considerations on Linux on http://www.securityportal.com/lskb/10000000/kben10000036.html, maybe it would be worth reading it.
Unfortunately, the article fails to mention that the noexec mount option
is basically useless.
$ /lib/ld-linux.so.2 /bin/echo eins
eins
$
...while /bin is on a noexec-mounted filesystem.
Roman.
