this is needed for newer USB enclosures to support trim
and get better speed. (already enabled on x86*)

the application layer gateway modules can used to bypass the nat
via nat slipstreaming. I had disabled all of them. If one is really needed
we can reenable it later.

This will increase throughput since BBR is more modern and adjusted to
the nowadays version of the Internet whereas Cubic is more conservative
and might not always fully saturate the downlink.

This will allow the kernel to seed its CRNG using RDSEED or RDRAND.
During the boot process, it is required that the CRNG is being
initialised, but it may take some long time on systems that do not have
a random number generator.
This is the default for various other distributions like Debian.

The kernel will try to gather entropy really early in the boot process
where those device drivers might not have been loaded yet. They are
small and can therefore be compiled into the kernel like we already do
on ARM.

ACPI (with EFI) is used on ARM systems conforming to the
Server Base Boot Requirements (SBBR) and is an optional
on embedded systems (EBBR).
Up to now the ARM64 boards supported by IPFire use U-Boot and
device tree so ACPI was not turned on.
The immediate use case here is to run under virtualization,
using my muvirt project[1] I can run IPFire on our Traverse Ten64
system. For reasons I'll explain separately it is not
currently possible to run stock IPFire on this system.
This change also enables the EFI RTC driver which is presented
by the qemu arm64 virt machine.

IMHO this can be safely disabled, as there is little if any need to debug
userspace programs _that_ deeply on an IPFire machine.

This is dangerous as it allows replacing the running kernel without
rebooting. Kernel Self Protection Project people recommend to keep it
disabled.

In my point of view, the last sentence matches our situation.
