However, I have to type the same passphrase four times, the two partitions while in initial ram disk and then again after the initial ram disk boots the operating system. Is there a way to only have to type the passphrase once? Any guidance would be greatly appreciated. Regards, John ^ permalink raw reply [flat|nested] 3+ messages in thread

See pros and cons of different approaches in the table at https://wiki.archlinux.org/title/Dm-crypt/Encrypting_an_entire_system#Overview With LVM on LUKS, you only need to enter the passphrase once to unlock the LVM. All partitions inside the LVM are automatically unlocked as a result. Hope that helps! Regards, Arun ^ permalink raw reply [flat|nested] 3+ messages in thread
