i am interested in encrypted filesystems and was wondering if xfs would be
good to encrypt...

my thoughts was to intercept the reading/writing of inodes from/to disk and
doing the en-decryption there...

the passphrase for the encryption would be entered during the mounting of
the filesystem (and deleted from memory during the unmount!)...

so my questions...

is there a technical reason why xfs is unsuitable for this???

has anybody thought about this before???

i have found a method called 'xfs_iflush_int' does all writing to the hard
disk go through here, or are there many places in the code that would need
to be modified for decrypting/encrypting???

is this a stupid idea??? :)


ps i hope this is the right place to send this message...
pps is there anybody else interesed???
