Can't mount squashfs loop during initramfs
I am trying to mount a squashfs file during initramfs.
I have included loop and squashfs modules.
Currently using mount /foo.squashfs /mountpoint
or mount -t squashfs -o loop /foo.squashfs /mountpoint
results with Error: block device required.
However, first setting up loop device manually with
losetup /dev/loop0 /foo.squashfs
then mounting with mount /dev/loop0 /mountpoint is sucessful.
I suspect I am missing a kernel module, but I am not sure.

Just go with the successful method. busybox can be weird sometimes. If in doubt, check lsmod before and after successful mount. Maybe strace it.

Currently I solved the problem by copying the 'mount' executable from the linux environment.

The reason ended up being, that the environment, on which I was building the initramfs. did not have busybox installed. Update-initramfs defaulted to using klibc, which did not have many features, including automatic loop mounting.
