Gentoo 3.3.4 with LUKS, initramfs Issues
Trying to get a new install running, have accomplished this before but for some reason the initramfs is giving me issues this time.
I am receiving a kernel panic indicating the system cannot find the init file.
The weird thing is it never prompts me for my password to decrypt the device. This leads me to believe that the issue is in my initramfs file itself.
I have tried both compressing my initramfs into a gzipped cpio and embedding it into the kernel, with neither working.
It has been a long day of troubleshooting this and any outside insight would be appreciated, thank you in advance.
my setup:
Code:
root sda3 (mapper/roo2)
boot sda1
swap sda2
kernel - includes devtmpfs
my initramfs dir:
Code:
├── bin
│** └── busybox
├── dev
│** ├── console
│** ├── null
│** ├── random
│** ├── sda1
│** ├── sda2
│** ├── sda3

├── etc
├── init
├── lib
├── mnt
│** └── roo2
├── proc
├── root
├── sbin

├── sys

my initramfs:
Code:
#!/bin/sh
rescue_shell() {
echo "Crap! Rescue Shell Time..."
exec sh
}
echo "Mounting proc sysfs and dev"
mount -t proc none /proc || rescue_shell
mount -t sysfs none /sys || rescue_shell
mount -t devtmpfs none /dev || rescue_shell
echo "Installing BusyBox"
busybox --install -s
echo "starting CryptSetup"
cryptsetup -T 5 luksOpen /dev/sda3 roo2 || echo "cryptsetup issues" ; rescue_shell

umount /proc || echo "umount /proc issues" ; rescue_shell
umount /sys || echo "umount /sys issues" ; rescue_shell
umount /dev || echo "umount /dev issues" ; rescue_shell
echo "Switching init"
if [[ -x "/mnt/roo2/sbin/init" ]] ; then
exec /sbin/switch_root /mnt/root /sbin/init
fi
echo "Failed to switch root, shell time..."
