[ale] ecryptfs problems switching OSes

[Jim Kinney]

Not fun. What does fsck do?

FYI: I have an encrypted / and swap on my laptop and an unencrypted backup.

With a backup tool like bacula, it is possible to keep an encrypted
backup as well. That would use a different key scheme from the drive
mount process.

It is also possible to simple do a backup of the encrypted files and
they recover nicely as encrypted files.

Yes. Talk od backups is late at this point in time...
