Two questions about LUKS in a file container
I'm thinking about putting my backup encrypted files in a LUKS filesystem within
a file instead of on a dedicated partition (for a few reasons).
I have two questions about that:
* if I don't have that LUKS filesystem "mounted" and open and I write to it,
I assume (or hope) that nothing will get written and I will get a warning or
error message of some sort?
* doesn't exactly apply to this situation, but, on the other hand, if my
"source" / original / non-backup LUKS system is in a file instead of on a
dedicated partition, and I use commands (like rsync or such) to copy the
unencrypted files not on the LUKS system, but I use options like the ones to
stay on the current filesystem (--one-file-system), I assume (or hope) that the
stuff in the encrypted partition will not get copied?
