My question says it all: on Ubuntu, is there any way to mount a .dmg file (as produced by OS X's Disk Utility) that contains an AES-encrypted, FAT12 filesystem?
I've seen sporadic advice about how to mount .dmg files containing hfsplus filesystems, so I'd have thought the fat12 (aka, "msdos") filesystem would be even easier. The closest I've come is:
mount -oloop,encryption=aes-256 -t msdos privatedmg.dmg ~/mounted
But this gives me the error
ioctl: LOOP_SET_STATUS: Invalid argument. I don't know much about linux filesystem mechanics, but am eager to learn!
