the yocto dev manual currently suggests that QEMU images come with

i don't have a QEMU image in front of me to test, but the definition
of the basic QEMU images doesn't seem to suggest that that's true.
i can see it's easy to add them, but the manual suggests they're
there by default. or am i misreading something?
It looks like we may need a manual tweak here.
core-image-minimal does not come with any ssh server. core-image-lsb
should have openssh instead of dropbear. So unless something changed
very recently, core-image-sato is the only one that has dropbear in
it by default.
Also, the manual states "The QEMU images also contain an embedded
Network File System (NFS) server that exports the image's root
filesystem." This isn't strictly true - instead we offer a native
tool which runs a userspace NFS server and if some prep work is done
by the user (extracting a rootfs tarball with runqemu-extract-sdk),
you can then point the runqemu script to that directory instead of a
rootfs image file.
rather than a simple manual tweak, what about actually adding one or
both of those features to even the smaller core images, then updating
the docs accordingly? just a thought.
Well, in the case of core-image-minimal, I don't think we want to add
additional bloat.
Also, when I teach classes on how to create custom image recipes, my
exercise is typically to take core-image-minimal, and modify it to
include an ssh server (dropbear or openssh) and psplash (which gives
students a nice visual change to notice when booting the new image). As
a fellow instructor, you may find that useful.
