Greetings Gentooers
I am setting up a new Gentoo system (on bare metal) and usually make a initrd by hand for encrypted root but its been quite a few years and hand rolling was always tedious compiling stuff with static-libs then recompiling without so figured I'd try out Dracut.
This install has a encrypted root inside an LVM logical volume. I know the volume and encrypted root are good because I can mount them from the live USB. And I do realize this is the reverse of the Gentoo way of putting lvm in the encrypted drive, but this is just a router appliance and I digress.
Things have not gone very smoothly with Dracut, at first I assumed dracut would copy over the needed kernel modules but it does not seem to do that.
Also it throws allot of systemd-cryptsetup not found errors even after I configured it
Code: | hostonly="yes"
# Equivalent to -a "module"
add_dracutmodules+=" lvm crypt " # Note leading and trailing spaces
omit_drivers+=" systemd systemd-cryptsetup bluetooth "

After I reconfigured the kernel like I used to with all the Lvm and Crypt stuff BLK_DEV_CRYPTOLOOP CONFIG_DM_CRYPT ... compiled into the kernel (not as modules but compiled in) Dracut was getting closer telling me my /dev/mapper/gentoo_root does not exist.
After somehow dropping to the Dracut rescue shell (which is apparently not busybox?) I can poke around and see something named my /dev/mappter/gentoo_root something slightly different, it prefixed the logical volume name.
So I was finally able to manually unlock my root partition and mount it under /sysroot
Poking around I could see it mounted and my files were there.
I then tried Code: | exec switch_root /sysroot /sbin/init | with no dice.
I possibly forgot to unmount proc sys and dev
So my question, how to you , finish booting from a Dracut rescue shell?
Should Code: | exec switch_root /sysroot /sbin/init | work?
Thanks in advance
