I decided to try the ezremaster tool today, but I'm getting the following error:
+ sudo mount /mnt/dm-1/craig/ISOs/tinycore/4.3/CorePlus-current.iso /tmp/ezremaster/mnt
mount: could not find any free loop device
+ exit 16
I'm using Micro Core 64 version 4.3.
losetup -a shows only 219 loop devices currently in use.
losetup -f returns "losetup: could not find any free loop device".
I have tried adding max_loop=256 without any success, though it sounds like this is no longer needed anyway.
