Can I mount encrypted home partition while booting with plymouth?

My home partition (NOT my root partition) is encrypted with dm-crypt. Since switching to systemd my boot-up process has felt a bit empty, compared to the old initscripts' boot text. So I installed plymouth and tried it out. I like it a lot, I would like to use it in the future! but my first test hit a snag.

I can't mount my home partition. The text prompt is not acceptable. I fell into "Emergency Mode," where I basically just removed the plymouth hook and rebooted again.

The plymouth_encrypt hook is no good for this purpose. I get a kernel panic because it expects my root partition to be encrypted, when it is not.

Is there a way to fix this problem? I just need to unlock a partition while booting, not my filesystem root. Surely there must be a way. If not, then the default way is good too.

That's because of the "quiet" boot parameter.

Isn't the home partition mounted from /etc/fstab? Maybe you missed something. Go back to whatever encryption wiki page you followed and see if there's any mention of fstab.

Re: Can I mount encrypted home partition while booting with plymouth?

My home partition is unlocked by /etc/crypttab

# crypttab: mappings for encrypted partitions
#
# <name>        <device>        <password>              <options>
home		/dev/sda7	none

And /dev/mapper/home is mounted by /etc/fstab

# /etc/fstab: static file system information
#
# <file system>		<dir>	<type>	<options>		<dump>	<pass>
/dev/mapper/home	/home	btrfs	defaults,compress=lzo	0	2

So if I stuck with plymouth I'd need to be prompted for my password on the splash screen before my home partition would unlock and mount.

Although, give me a moment to reboot without "quiet" and see if that is to my liking instead...

Okay, I do like that a lot more than the quiet boot up. It feels nice and linuxxy. I am now appeased...

But I don't think I should mark this as solved yet, since the original question remains unanswered. What if someone else in the distant future has the same problem, and there is somebody alive today who has the means to help them?
