Absolutely. In the LEAF model model the core packages and startup configuration data are in write-protected space, so that in worst-case scenario, you power-cycle the router, and you're back to a known state. Most other embedded systems I am familiar with have local persistent read/write storage (hard drive, CF, USB flash, etc.) that contains the running AND startup configuration data (This includes expensive name-brand enterprise grade routers.) A power-cycle doesn't give you the warm fuzzy that the rootkit is gone. :-) In my heart, I believe the LEAF model is the safer route. Not perfect, but it adds an additional layer of "defense in depth". While I completely respect those that want to run a router off of a 1.44MB diskette drive, some of us want squid, dansguardian, and samba running (on a local hard disk) AND we want the warm-fuzzy of knowing we can reboot the box to a known state. (And yes, I have a system that boots from CD-R, partitions the hard disk, formats it, and then makes the cache directories for squid before squid.lrp is loaded. And no, you don't call it a router at that point. But I still like to think of it as a LEAF box. :-) ) It would be nice to scale the LEAF way of doing things up, rather than abandon it because we have "larger media needs" or because we need 24x7x365 uptimes. As I said in my original post: "Or, then again, its possible I've just completely lost it." I have a need for enterprise configuration management; but I'm also sensitive to the fact that the LEAF community may not have those same needs. Paul, I sincerely appreciate your comments.
