Subject: [gentoo-security] mount noexec and ro

Hello,

can/does mounting a partition with noexec, ro etc. provide additional 
security or are those limitations easy to circumvent?

Example: webserver running chrooted
all libs and executables (apache, lib, usr ...) on read only mounted 
partition /srv/www, data dirs (logs, htdocs ...) on 
partition /srv/www/data mounted with noexec (but rw of course), no cgi 
needed.
Server is started with "chroot /srv/www /apache/bin/httpd -k start".

Any cognition? Is this useful, nice, nonsense?
Keeping the chroot updated and so on is not my concern here.

Thanks, Joe
