live-build commit 24aab15d2a133075992ce3a216b1c3476dc7bd4c has added
generation of speech synth entries. this ensures that with the next
release of live-build, the kali one is not added as a duplicate.
note that live-build commit a25b77e0998ac455b48c8c523a08bd282229fb49
removes "video=vesa:ywrap,mtrr" from the entries it generates, so lack of
that is deliberate should you later compare the differences and wonder
about it.
ref: debian bug #775128
done in live-build auto-generated menu entries back in v5.0a3 for syslinux
(ba6b9adeff634845a9ab7cbd5218257a7aa254ab). was missing for grub entries
until a33938f8d47f23c23335ecf671b1db9afcd0b726 and
aadf8c4cacecc4664412c6bbc7b8e039e1dd772a.
debootstrap's change that enabled this feature got reverted
and now our live-config scripts are no longer used. Make sure
to put them back at the correct place when needed.
