livecd-iso-to-disk & editliveos: Expand partitioning and filesystem support
by Frederick Grose 09 Feb '21

09 Feb '21

See https://github.com/livecd-tools/livecd-tools/pull/176. A cumulative update, best reviewed by testing. Enable formatting of a separate EFI System Partition and Apple HFS+ boot partition based on the files efiboot.img and macboot.img in the /images directory of the source. This means EFI booting is possible with overlay sizes as large as the free space on the primary partition. Support F2FS type formatting for the device root, home, or overlay filesystems. Provide boot support for F2FS-formatted discs with an EFI Boot Stub loader from dracut, as GRUB support for F2FS is faulty at this time. Allow conversion of the root filesystem type between ext[234], btrfs, xfs, & F2FS and their available block sizes with editliveos. Allow a Device-mapper target to be the target device for installation. This would enable concurrent multi device installation through a preconfigured Device-mapper mirror target. Also, - introduce the --noesp option to --format to avoid the extra partitions; - on UEFI booted hosts, offer to create a UEFI boot entry for F2FS-based installations; - do not require SYSLINUX-EXTLINUX on the installation host; - take greater advantage of BASH case statements for code structure; - use fallocate on filesystem creation to reserve storage space for embedded filesystems; - add a trap ERR line for error reporting in livecd-iso-to-disk; - provide better support for isoscan/filename boots from .iso files; - delete the uncompressed image file just after compression to make more space available, if preservation of temporary files is not selected; - use bind mounts for /run, /sys, & /dev in liveimage-mount; - update documentation. ref: ... as GRUB support for F2FS is faulty at this time. I found that the following command run against a livecd-iso-to-disk installed LiveUSB, sudo grub2-install -v --boot-directory=/run/media/ \liveuser/ESP/EFI/BOOT --compress=xz --modules="part_gpt part_msdos f2fs" --efi-directory=/run/media/ \liveuser/ESP/EFI --no-bootsector --removable -s --target=x86_64-efi --recheck /run/media/liveuser/ESP/ produces a BOOTX64.EFI that recognizes the F2FS filesystem on listing (hd0,gpt1) but scrolls blank lines continuously when listing (hd0,gpt1)/ I suspect that f2fs.mod is not fully compatible with f2fs ver 1.14. Confirmation and followup on this would be appreciated. I haven't been able to locate the source code that specifies the modules included in the EFI boot loaders that are provided with the Fedora Live .isos. A pointer to that would be appreciated too.

Unable to login into custom live image
by Sreyan Chakravarty 01 Jan '21

Hi, I have created a custom live image using livecd-creator, but when I boot from it there is no way to login into KDE after that. I have tried adding: %post cat <<FOE > /etc/sddm.conf.d/autologin.conf [Autologin] User=live-user Session=plasma.desktop FOE %end But I get the message: ignoring %post failure (code 1) /tmp/ks-script-xntc2id7: line 1: /etc/sddm.conf.d/autologin.conf: No such file or directory My kickstart file is very basic and I have not added any packages that would cause problems. Even building an image without any modifications causes a login problem. -- Regards, Sreyan Chakravarty
