#636 Issue `closed`: Fedora23 ISOLINUX does not boot¶

Labels: bug

gdha opened issue at 2015-08-13 10:45:¶

The CD image on Fedora23 (alpha) contains:

# ls /mnt/isolinux/
boot.cat  initrd.cgz  isolinux.bin  isolinux.cfg  kernel  message  rear.help

but the syslinux version is 6.03 which means we need also ldlinux.c32 and on fedora23 it is present under directory /usr/share/syslinux (not yet modular as under Ubuntu 15 and Debian 8). rear thinks it is legacy syslinux and do not copy the ldlinux.c32 to the isolinux CD boot image.

Just inspected the live F23 CD:

$ ls /mnt/isolinux/
boot.cat  grub.conf   isolinux.bin  ldlinux.c32   libutil.c32  splash.png  upgrade.img   vmlinuz
boot.msg  initrd.img  isolinux.cfg  libcom32.c32  memtest      TRANS.TBL   vesamenu.c32

We have fixed the path in the meantime, but still no luck with booting the rescue image created on F23 - content seems good:

# isoinfo -f -i /var/lib/rear/output/rear-localhost.iso

and ISO seems bootable too:

See http://www.syslinux.org/wiki/index.php/Library_modules
Added liblua.c32 but also with that liblua.c32 (insolinux in debug mode):

isolinux: Main iname LBA = 00000025
isolinux: Image read, jumping to main code...

nothing happens anymore

In Fedora 23 beta release it works again - great! The bugzilla nr above has been closed as-well.
