Comment 4 for bug 1842417

I think some problem has to be considered: as far as I understood, the folder /.fscrypt shall not be deleted (risk to loose access to your data?)
if yes, it's a bit risky in case you re-install system on / with a separated encrypted /home that you want to keep.

I also would like to add an other issue of full disk encryption: it need to enter password at boot on the machine...it cannot be done remotely.
So if you need remote connexion to a powered-off device (with wake on lan) or a rebooted device (for example due to power interruption), it's not possible.
