[Bug 2038694] Re: Now that exfat filesystem is in the kernel, allow using it for storing isos loopback booting and storing the persistence file

[LAFFITTE Guy]

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.

Title:
  Now that exfat filesystem is in the kernel, allow using it for storing
  isos loopback booting and storing the persistence file

Status in casper package in Ubuntu:
  New

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.
