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

When you say "root shutdown unclean": How do you shutdown, and what are you seeing?

Can you point to a reference for this bug?

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

[1] >>

I have a setup with the root partition in a logical Volume of LVM on top of LUKS (whole disk but /boot)

Yes, that’s what I had as well. /home was included in the root partition. Swap was a separate encrypted partition in the LVM. << [1]

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
