how do i set up automounting encrypted partition?

[picarica]

so i would like to make my openrc or grub to automatically mount my /home encrypted partition but that it will still ask for passphrase
now i get error at but that dolvm couldnt found any lvm partition, i have this in my defaukt/grub

Rather than mounting it at grub level, do it via openrc. Configure /etc/conf.d/dmcrypt accordingly and make sure the dmcrypt service is started at boot level.

Moved from Installing Gentoo to Duplicate Threads in favour of fstab cant mount my encrypted /home partition.
