OK, the assumption here is that the box actually gets compromised with
write access. Not a big deal on a 2 interface SOHO implementation, but
a large PITA if your running >4 interfaces and a lot of userspace programs
and getting paid to fix it. There are LEAF boxes out there using ~20
interfaces. WriteProtection gives you something to compare to, and a base
to change to eliminate the hole when it is found. You can wipe out a back
door and buy atleast a little time to update your image with a reboot.

Writeprotection is not an ultimate security implementation, rather it is an
optional tool that is available for those who want it. The LEAF developers
tend to try to stay with a floppy image to hone our development skills, this
is not mandatory as reflected by what the mailing-list archives show. In fact,
IDE has been available since Eiger. 

What is the difference between a minimal Debain/Slackware install and a full
LEAF install? If running on IDE and having the maximum amount of available
packages is more important than the core of security options we've decided 
on, I don't feel you would even be posting to this list. Always remember, your
idea of a 'secure system' does not necessarily relect anyone elses opinion.
We try to provide what options we feel are desired and/or needed. If the
floppy disk does not work as a target media for you, don't use it.... nobody
here will really care. There has been glibc-2.2.x IDE images available for
atleast a year, are you using one? If not, why?

I'm afraid that developing for IDE only will allow many of us to become lazy
in developing small-footprint applications. Fortunately I can say that this is
not the case right now.


Since I last added a new ipsec tunnel on my personal home Dachstein box:
firewall: -root-
# uptime
 06:16:29 up 88 Days (2122h), load average: 0.00 0.00 0.00

I had uptime over 6 months with my old Eigerstein floppy box until a power 
failure.
