ubuntu# ecryptfs-migrate-home --user yogiyo   INFO: Checking disk sapce, this may take a few moments. Please be patient. INFO : Checking for open files in /home/yogiyo Enter your login passphrase [yogiyo] : _

 

Some Important Notes! 1. The file encryption appears to have completed successfully. however, yogiyo MUST LOGIN IMMEDIATELY, _BEFORE_THE_NEXT_REBOOT_, YO COMPLETE THE MIGRATION!!! 2. If yogiyo can log in and read and write their files, then the migration is complete, and you should remove /home/yogiyo.knSmoySm. Otherwise, restore /home/yogiyo.knSmoySm back to /home/yogiyo. 3. yogiyo should also run 'ecryptfs-unwrap-passphrase' and record their randomly generated mount passphrase as soon as possible. 4. To ensuure the integrity of all encrypted data on this system. you should also encrypt swap space with 'eccryptfs-setup-swap.'   ubuntu# reboot now
