What is the use for putting the partition table in the kernel command line?
It says it saves space by not needing the mbr, but doesn't this mean that the partition table is moved somewhere else instead, since the bootloader needs to read it and generate the kernel command line anyway?

Think embedded systems where you may have some small flash device with your bootloader/bootloader settings (and kernel command line) and a SD card for the root filesystem.

I believe it's good for partitions on flash that need to be aligned to some large blocks. It's better to sacrifice a hundred bytes in CMOS and in RAM than to lose 256k on a system that is tight on the flash space.
