How to relocate Home Drive | Ubuntu

Created an encrypted partition on my workstation (Ubuntu 18.04).

So, went to relocate the Home Folder.

$ rsync -aXS /home/user-a/. /media/datastore/home/user-a/.

$ usermod -m -d /media/datastore/home/user-a username

$ sudo dpkg-reconfigure apparmor

$ cat /etc/apparmor.d/tunables/home.d/ubuntu

@{HOMEDIRS}+=/media/datastore/home/

$ sudo rm -f /etc/apparmor.d/cache/*

$ sudo rm -f /var/cache/apparmor/snap.*

Not work, however.

cannot create user data directory: /media/datastore/home/user-a/snap/knowte/1: Permission denied

Finally, it worked from  /home/user-a  back to:

/media/datastore/home/user-a /home/user-a    none    defaults,bind    0    0

/etc/fstab:

UUID=75c68d85-f74e-492a-a698-07a866b223b4    /media/datastore    ext4    defaults    0    0

/media/datastore/home/user-a /home/user-a    none    defaults,bind    0    0

/etc/crypttab:

luks-75c68d85-f74e-492a-a698-07a866b223b4    /UUID=75c68d85-f74e-492a-a698-07a866b223b4    none    luks
