For home desktops, usually -STABLE is a good solution. Server
maintainers tend to use -RELEASE-pX (which also makes binary
updates easier).

It's worth mentioning that it's not good practice to have a
keyfile-based decryption which is "unlocked" by a USB stick
permanently sticking in the server. Security is nearly zero
in such a constellation. Passphrase-based decryption is good
as long as you have physical access to the server and only
you (and maybe those you trust) have a secure (!!!) password
which needs to be entered manually at system startup to "unlock"
the /home drive or partition.

Good you spotted it - of course there is no need for journaling in
this case (too much writes, no real benefit).
