The Linux boot image is a squashfs image loaded into memory by your boot loader (eg grub). It can still mount other filesystems for on-disk partitions (provided the relevant file system and drivers are compiled into the kernel). 50MiB is a bit on the heavy side for many embedded use cases (ie M0 devices). It’s possible M3/M4 CPUs have enough storage and RAM to support this. It’s been a while since I checked the specs for those chips.

Embedded is a broad category. Yeah, this is a bit heavyweight for Cortex-M, but so is Linux just kind of in general. This would be great for a Cortex-A class SoC.
