Ubuntu using file casper-rw image file to save change content

The Yumi tool can be used to make a persistent boot disk based on the U-disk

CASPER-RW is an Ubuntu-specific feature that supports LIVECD-enabled Ubuntu system to save users ' change content

Do we want to start with the ISO CD from the hard drive and use the CASPER-RW image file to be feasible? After long-term research, experiments, the answer is feasible, but there are certain limitations

Feasibility:

　　Boot to live mode with grub4dos support for Ubuntu ISO files , and can save changes using CASPER-RW files

Limit:

The ISO file and the CASPER-RW file must be on the same disk partition, and the partition must be in FAT32 format

Example: The key point is on the settings of the persistent, Persistent-path parameters

Note:

In fact, as long as the volume label of a Ext{n} partition on a disk is casper-rw,ubuntu automatically uses that partition as the destination for Persistent-path
