If you rebuild from source you shouldn't need the hotpatch because I
submitted a fix to inithooks.
Unfortunately I think I forgot to ask Alon to update the archive with
inithooks so if you rebuild in TKLDev you'll still be getting the old
package.
As a dirty workaround you can drop the updated 10regen-sshkeys file from
the fixed inithooks into overlay/usr/lib/inithooks/firstboot.d.
FWIW, in the next version of TKLDev we'll roll in a feature that makes
it easy to build packages from source based on the scripts we use to
generate the archive so that you don't have to wait on us to do that.
The fix is in inithooks
