BSDIFF for Slax 6.0.3 

$ bsdiff
bsdiff: usage: bsdiff oldfile newfile patchfile
$ bsdiff slax-6.0.2.iso slax-6.0.3.iso slax-6.0.2-to-6.0.3.iso.bsdiff
Killed

Why it get killed — my computer almost choked:

$ uptime
 23:43:24 up 1 day,  6:08,  8 users,  load average: 15.95, 5.96, 2.16

After it get killed:

$ uptime
 23:43:44 up 1 day,  6:09,  8 users,  load average: 15.65, 6.54, 2.44

The bsdiff file is more than a third of the iso file. So for me it is much better to download the iso instead.
