Hi, > PS: You can fetch the image from the known location to test
Looks good. Viewing xorriso arguments in /mnt/iso/.disk/mkisofs ... looks good too. The ISO is now added to my collection of bootable ISOs for regression test. My test loop checks whether the ISOs which are repacked from existing ISOs still show the same boot equipment and file tree content. (Happens when i change boot related program parts and before releases. 2 hours of 3.5 GHz Xeon shoveling forth and back on about 150 GB.) May i assume that the old debian-10.0-sparc64-NETINST-1.iso is in retirement for now ? (Please announce on debian-sparc if the genisoimage style gets revived.) > boots with GRUB on CD. SUN disk label is actually a hard disk thing. Are there machines which boot from USB attached disk storage ? Have a nice day :) Thomas
