[Bug 2038694] Re: Now that exfat filesystem is in the kernel, allow using it for storing isos loopback booting and storing the persistence file
Previously I created a script to make ubuntu iso images bootable from f2fs partitions. After discovering this bug, I converted it into a generic "make casper aware of fs X, add kernel modules Y to the initrd" one. You can get it here https://github.com/slowpeek/ubuntu-remaster-bbb and make 20.04+ images bootable from exfat like this: ubuntu-remaster-exfat input.iso output.iso or, without the exfat shortcut: ubuntu-remaster-bbb --fs exfat --module exfat input.iso output.iso If using the docker image: ubuntu-remaster-bbb.docker --fs exfat --module exfat -- input.iso output.iso This way 18.04.5+ can boot from exfat as well, but only with the hwe kernel. Hence in case of live-server 18.04.5+, extra '--hwe-only' option is required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2038694 Title: Now that exfat filesystem is in the kernel, allow using it for storing isos loopback booting and storing the persistence file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/2038694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Adrian Feliks (mexit) I've just filed a similar bug about f2fs.

@Adam Vodopjan (grozzly) You're absolutely right. Currently, booting from exFAT doesn't work because there's no module for it, neither built-in nor located in early3/usr/lib/modules/6.8.0-11-generic/kernel/fs. The command `manual_add_modules exfat` (patch @Glenn Washburn) adds exfat module to the initrd during livecd creation.

@Adrian Feliks (mexit) How is it supposed to work with just that? Looking into initrd of 24.04 daily unpacked with unmkinitramfs. According to main/lib/modules/6.8.0-11-generic/modules.builtin, exfat is not a builtin module. And there is no exfat in early3/usr/lib/modules/6.8.0-11-generic/kernel/fs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2038694 Title: Now that exfat filesystem is in the kernel, allow using it for storing isos loopback booting and storing the persistence file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/2038694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
