I have spent what feels like half my life doing automatic installs. I
care a lot and I understand the requirements. I also see through
misstatements about reality used to justify stupid design decisions.

For automated installs you don't have to satisfy me. Feel free to
deliver a lousy solution to your users. Just don't use your arbitrary
design decisions to justify your kernel patches.

Non-interactive installs do not justify removing all trust from the root
user of a system, disabling suspend to disk and completely rewriting
kexec for the simple expedient removing a couple of lines of code from
your bootloader.
