Boot from nfs

[mk01]

10 minutes back I was sure you will ask that.

yes, it is like soft and hard quota limit.
this parameter is soft. it means if YES it will not remove initramfs usage if manually added. but it won't add it, if does not exists (config.txt initramfs entry).

sounds a little silly now, but was making sense at the time of implementation. during-shutdown code is trying to guess if next boot can be direct via kernel. FORCEINITRAM=yes will break the process in case system decides to boot without initramfs.
