Huh?
There is an entire universe of embedded devices out there. Vendors refer to
this as the 'internet of things', for commercialization and mindshare
purposes. It is actually just embedded devices, with tcp/ip/udp.......
So there are trillions of reasons for gentoo folks to pursue minimization
all the way down to a stripped (optimized) linux kernel to the point of
running embedded linux. Just take a look at Linaro.

One of the (I guess not so obvious) purposes of my recent thread on profiles
is for the community to discuss profiles that are less than the default
profile for a given arch. We should be able to readily move up (from an
embedded) and down (from a default profile), on each and every arch, with
just the minimal flags, configs and such. Default is not even close to
minimal. I'm just surprised (mildly disappointed :: but not really) that one
of our embedded devs has not already championed this issue.
David is just pointing out yet another reason for a different minimization
need, but still in-line with what I outlined. I just think that the gentoo
community should not have to go it individually alone when such
minimizations are desired.
Beside just as gentoo teaches one the basics of linux, so do does one learn
about hardware issues, when you run an embedded system on a given platform.
However, I do understand that *everyone with any sort of embedded expertise*
is now mostly focused on the possibilities with the new arm64 SoCs about to
appear on the market.
hth,
