Bug Description
Recent Ubuntu Desktop livecd isos are greater than 4G and have been growing at an alarming rate (22.04.1 is 3.6G and 22.04.2 is 4.6G, but that's another story). The fat32 filesystem allows a maximum of 4G file size, so newer isos can not be stored on fat32. Currently the only non-journalled filesystem and only file system with easy interoperability with Windows is fat32. Neither NTFS nor EXFAT are supported by casper. EXFAT would be good to support so that a windows user can write a greater than 4G iso file from Windows to use for loopback booting. And likewise allow the persistence file to be on EXFAT, so that another filesystem is not needed just to store the persistence file.

In my opinion, NTFS is not interesting at all, because it is too close to hell.
On the other hand, EXFAT seems to be a very good choice for persistence files, especially when you want to install several distributions with persistence on an external USB disk or SSD. All persistence files will hold in a large EXFAT partition with a directory for persistence files of each distribution.
