Hello,
I installed F10 last night. Install went file. The machine was previously running F9 with encrypted /root and /home. For the install on F10 did an install, not upgrade, and formatted /root. Left /home alone.
During the boot process I get prompted for the passphrase to unlock the encryption for /root. Once the system gets to the interactive boot process and does the check disks routine I do not get prompted to enter a passphrase to allow access to the encrypted /home.
I get the following error then it drops me to a maintenance prompt.

I've verified through in maintenance mode that /etc/crypttab looks fine and the same with /etc/fstab. I can unlock my encrypted /home by running cryptsetup luksOpen /dev/mapper/VGSys-LVHome luks-d8590a73-6fd0-46e5-8135-3ad739f58f6c and providing the passphrase. I then can mount /home. So I know things with that are good and the data is there. The problem is that during bootup it just doesn't prompt for the passphrase to unlock /home.
From what I can tell /etc/rc.sysinit is responsible for mount partitions and in the case of encrypted volumes asking for the passphrase. I'm wondering if this is a bug.
Any help is appreciated.
Here's what I had to do. I don't think I should of but I guess that just means that I will be filing a bug report. The problem had nothing to do concerning LUKS. It appears it had to do with how fcsk is run on bootup. Now I assume it had something to do with the fact that I am running LVM and LUKS, but I don't know. In the new /etc/crypttab that F10 created during the install was the following lines:
luks-ce0e45d5-c705-4fde-8f7d-a17172c39aae UUID=ce0e45d5-c705-4fde-8f7d-a17172c39aae none
luks-d8590a73-6fd0-46e5-8135-3ad739f58f6c UUID=d8590a73-6fd0-46e5-8135-3ad739f58f6c none
What I didn't see initially because I couldn't read fast enough was that fsck was complaining about not being able to find UUID=ce0e45d5-c705-4fde-8f7d-a17172c39aae. Once I commented some lines out of /etc/rc.sysinit and fooled around there. I was able to see that. So the change I made to /etc/crypttab was to remove the UUID and replace it with the direct position.
New /etc/crypttab
luks-ce0e45d5-c705-4fde-8f7d-a17172c39aae /dev/mapper/VGSys-LVRoot none
luks-d8590a73-6fd0-46e5-8135-3ad739f58f6c /dev/mapper/VGSys-LVHome none
After I made that change and put the original rc.sysinit in place the system booted up without issue. I was able to modify /etc/crypttab by booting off the install media and using the rescue mode. I did have to manually mount /.
