Hello Klaus,
do you plan to implement the possibility to boot from exFAT USB flash
disk?
exFAT is supported accross modern systems (OS X, Linux, MS Windows) and
it is a pitty to limit the nowadays' huge flash disks by FAT32's max
file size of 4 GB. (I put KNOPPIX on a regular flash disk that I also
use for data.)
I guess it would require a different boot loader (Grub 2.x, possibly
others), static binary mount.exfat-fuse and a slight adjustment of
init's trymount() function in minirt.gz. And of course update of
flash-knoppix script. (It works for me, though I used dynamic binary
mount.exfat-fuse with all the library dependencies.)
regards,
Milan
