I use xubuntu 13.04
wiped away ~/.Private
files folders inside home wiped away except /Documents
tried reboot, it logged out instead. logged in,
new folder structure in home folder.
shut down
rebooted with live cd
ecryptfs-recover-private
didn't ask mount passwd but logging in pw
opens the new structure instead of  the lost structure

it's quite easy to attack home folder and wipe away the .private folder, also .Private can be accidentally deleted by user.

what to do in case if ./Private gets lost?
