Moving this to a separate thread as it’s nor really related to switching to
TDE.

While I did mention the issue on the Devuan user mailing list, I do not know
if there is a bug report for it. It may be the issue Stefan references, but,
if so MX Linux has patched/solved the issue on their own as I do not see it
with MX Linux.
To maintain due diligence for client NDAs I must use encryption, or some other
method, to safeguard their data. As such, I no longer have Devuan installed.
Bill (I think it was Bill, sorry if I’m mis-quoting) is entirely right though,
I have never seen any of the lags or hangs with Devuan or MX Linux that the
systemd versions of Debian are fairly well know for.

Here are my remembrances from a month or so ago. Obviously these are not the
exact message phrases.
Observations:
- Install Devuan selecting automatically use full disk and encrypt
[everything]. [1]
- In the Software Selection only select:
- - Console productivity
- - Standard system utilities
- - (e.g. Un-check everything else)
- Install TDE
- Boot normally

Yes, that’s what I had as well. /home was included in the root partition.
Swap was a separate encrypted partition in the LVM.

Best guess: Since so little is installed, you don’t have the usual
startup/shutdown splash screens that usually ‘hide’ any of the
startup/shutdown scrolling messages. Try hitting ‘Escape’ if you have splash
screens hiding the messages?

During shutdown you will see messages somewhat similar to what Stefan shows,
but they are closer to this and explicitly say “[FAIL]” in red:
“Unmounting {root partition name} [FAIL] ... [FAIL][FAIL][FAIL][FAIL][FAIL]”
It hangs for several seconds (15?) on the first [FAIL] and then re-tries
enough times to wrap the line.
- I shutdown approximately 13 times after noticing the first [FAIL] message
where I explicitly watched the shutdown messages.
- Of the boot up sequences I explicitly watched (10+) there were 3 instances
of fsck(?*) finding and fixing errors on the root partition.
* The messages go fast, I’m fairly sure is was fsck, but it could have been
anything really, my knowledge of the actual boot process is pretty weak.

That’s as best as my memory gives me. If you install Devuan with Full Disk
Encryption (FDE), it’s really easy to spot, just watch a shutdown.
Okay, I’ve got to get back to work :( If there’s more Q’s, ask, but it’ll be
a few days or next weekend before I get to them.
Best,
Michael
