@karasu Woohoo! Thanks a ton karasu! That seems to have worked.
For anyone else in the future that wants this, note that I had to edit both the /etc/crypttab file, as recommended by karasu, but also the /etc/fstab file.
In crypttab I had to specify the UUID of the encrypted drive. In fstab I had to specify the UUID of the ext4 filesystem of the decrypted volume-- in fact there was already a line for /home in fstab, but it had the UUID of the encrypted partition rather than the UUID of the ext4 filesystem that is on the encrypted drive. So I just had to change the UUID in that line. To get the UUIDs, I ran
lsblk -fto get the relevant UUIDs after mounting the encrypted volume during the live USB session.
@karasu I just tried option number 2. Perhaps I’m doing something wrong. In Antergros live USB, I used
cryptsetupto load and decrypt the HDD. Can browse it, write to it, etc. from file manager without issue. Using Cnchi then I set sda1 to /boot, sda2 to / and sda3 to swap with the option to format, then sdb1 to /home as ext4 (which is the fs when decrypted), with the option to NOT format. Nowhere in the install process does it ask for my decryption password.
After install completes and I restart, my laptop boots to emergency mode where it prompts me to log in as root for maintenance. It appears that it is expecting sdb1 to be ext4 but is not finding that filesystem since it’s an encrypted drive.
Fedora’s installer asks for the decryption key when i specify the /home directory is an encrypted volume when installing fedora, and it boots then to a screen where i enter the password for decryption. Neither of these things occurs with Antergos.
Any ideas as to what I am doing wrong?
What is the process for installing Antergos with a previously existing /home partition?
I am coming over from a Fedora install where I had /, /boot, and swap on a 128GB SSD and /home on a LUKS encrypted 750GB HDD. I’d like to install Antergos on the SSD and point it to the encrypted HDD for the /home partition. In the installer Cnchi there are options to encrypt your home partition, but I’d like to avoid the issues that this user ran into with duplicating encrytption. There’s also options to specify a previously existing /home partition and the file system, but LUKS is not one of the options there.
So what are the steps to accomplish this?
I came across this post about accomplishing this when LVM is in use, but I was unsure whether this would do the trick since I’m not using LVM. Do I just follow that tutorial and simply skip the steps having to do with LVM?
Thanks in advance.
