Hi Guix,
I've noticed that recently (unfortunately, I don't know exactly when it
started), that grub no longer prompts me to enter my password to unlock my
root filesystem. I notice that at the grub command line, if I enter
`cryptomount -a`, I am not prompted for a password, and the root
filesystem does not become available. However, if I first run `insmod
luks` and then `cryptomount -a`, I am prompted for my password, and the
root filesystem become available and I can boot normally.
Therefore, it seem like grub is not auto-loading the luks module for some
reason. Why might this be the case? What needs to be changed so that luks
is auto loaded?
Best,
Jack
