[LEDE-DEV] mount_root skipped on initramfs builds

[Josua Mayer]

Hi everyone,

During my work on supporting a block-device as overlay partition,
without using extroot I came across this phenomenon:

When booting my mvebu-based board with an initramfs, mount_root was not
executed. This seems unusual to me, I certainly expected the init
process to be exactly the same.
So I traced the cause to line 15 in the 80_mount_root preinit script.
It says: [ "$INITRAMFS" = "1" ] || boot_hook_add preinit_main do_mount_root

Very clearly, this behaviour is intentional. Would anyone be willing to
shed some light on why this is?
Can it be removed? And if not: What is stopping us?

John I added you in CC because it is your commit that added the
initramfs-check:
