Probe at runtime instead of buildtime - Include all drivers, not just
the drivers necessary for the hardware being run. (For storage, the
common ones will be built-in to the kernel anyway)
This means include all storage drivers and firmware for the storage
drivers?
By default, yes. As of yesterday or so, there's support for
overriding the set of modules if you want a subset since I figure
someone someday will want it and it's trivial to allow.
Does this also mean we only add network drivers if the initrd is
explicitly built for netboot?
There are many open questions for exactly how best to handle netboot.
I expect the answer is "yes" and that we end up wanting to have the
config for the initramfs to specify things like
nbd_boot="yes"
nfs_boot="yes"
iscsi_boot="yes"
etc so that people can tweak accordingly. It may also be that we want
it to be based on the presence of things installed on the system.
How do we plan on dealing with the location of various standard
utilities being different on other Linux distributions?

Perhaps use "which" to find it? But then how do we choose its
destination path in the initrd chroot if the distributions disagree
on where they expect a command to go? Will they disagree?
which will work just fine (although your examples are ones that don't
matter right now :). And the destination path should match the source
path. We just have to ensure $PATH is appropriate in the initramfs
