How to mount a squash image as a root file system?

I am trying to update a custom initramfs init script to mount a squashfs image as the root file system.

How to mount a SquashFS file to a USB?

Unpack the file then move it somewhere else (so you still have it as a backup): Go in squashfs-root, add/modify as per your taste then recreate filesystem.squashfs: copy the newly created filesystem.squashfs over the existing one on your USB drive, e.g.: then reboot and use your LIVE USB.

What is Ubuntu Squashfs-tools?

Squashfs is a highly compressed read-only filesystem for Linux. It uses zlib compression to compress both files, inodes and directories. Inodes in the system are very small and all blocks are packed to minimize data overhead.

What does mount loop mean?

A “loop” device in Linux is an abstraction that lets you treat a file like a block device. It’s specifically meant for a use like your example, where you can mount a file containing a CD image and interact with the filesystem in it as if it were burned to a CD and placed in your drive.

It is a read-only file system that lets you compress whole file systems or single directories, write them to other devices/partitions or to ordinary files, and then mount them directly (if a device) or using a loopback device (if it is a file). The modular, compact system design of SquashFS is bliss.

When to copy files from SquashFS to ram?

Example some files in /usr or /var will be copied over to ram during the boot process, unless the liveCD implemented an overlay filesystem like auFS or overlayfs with the former being used in the Gentoo Linux liveCD which doesn’t required copying directories from its squashfs image.

Mount them together as an overlayfs to your system — Now you can add/modify files in /fin. Once everything done, you can mksquashfs /fin to a new squashfs file, , then clear/unmount all the other used directories as you will. The squashfs and some unionfs are commonly used for a live-cd.
