IPv6 is optional though, Lennart says you can blacklist the module.  If 
it acts gracefully if IPv6 is not builtin or installable by module then 
all is well.

"Embedded" as an argument needs a lot of care.  It means several very 
different things, but many of those things are out of scope for Fedora, 
eg, ARM7.  (Use busybox there ^^)

For what's left, eg ARM9+ that you can run normal Linux and Fedora on, 
ipv6 is going to be workable if the memory allows.  Looking a year or 
two ahead, where "Embedded" will extend to Cortex A15 quad core, and 
IPv6 will presumably have gained traction, the tradeoffs involved with 
cutdown environments like busybox / dropbear and IPv4-only are going to 
start being harder to accept.

So while it's super healthy to press system tools on bloat, it is quite 
possible to deploy the "Embedded" argument to go too far and conflict 
with what Fedora is and trying to do overall -- and what other Embedded 
guys will want from it in future.  "Embedded" is generally converging 
towards the kind of full strength systems we use on x86 today.
