Here it is:

>From arch/x86/boot/install.sh:

...
# User may have a custom install script

if [ -x ~/bin/${INSTALLKERNEL} ]; then exec ~/bin/${INSTALLKERNEL} "$@"; fi
if [ -x /sbin/${INSTALLKERNEL} ]; then exec /sbin/${INSTALLKERNEL} "$@"; fi
...

so distros *usually* should supply a custom, distro-specific
installkernel script which does that. The distros which you are seeing
it on simply don't have that script installed and I need to talk to
distro people as to what the rule there is for supplying such a script
now.

Because most distros should supply it though and those new distros
dropping it looks like some new "strategy" or so.

We'll see.
