vaav,
Think of the initrd as being a completely separate install to your real root. It is.
It borrows binaries because that's convenient but it doesn't have to.
e.g. genkernel all builds its own binaries for the initrd.
Do not mask udev.
/sbin/lvm shows that it needs libudev.so.1. That's fine.
The udev service will not be started in the initrd and udev will not make any adjustments to /dev for you.
Its not runnning, so it cant,
| Code: | | nod /dev/nvme0 0660 0 0 b 8 0 |
looks wrong.
The means a block device with kernel major number 8, minor number 0. That's /dev/sda
From your
| Code: | $ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
nvme0n1 259:0 0 119.2G 0 disk
├─nvme0n1p1 259:1 0 699M 0 part /boot
└─nvme0n1p2 259:2 0 118.6G 0 part
└─root_nvme0n1p2-Hellovaa-root 253:0 0 118.6G 0 crypt
├─Hellovaa-swap 253:1 0 8G 0 lvm [SWAP]
├─Hellovaa-root 253:2 0 32G 0 lvm /
└─Hellovaa-home 253:3 0 78.6G 0 lvm /home |
You need | Code: | | nod /dev/nvme0 0660 0 0 b 259 0 |
Check your other nod entries too.
| Code: | # libraries required by /sbin/fsck.ext4 and /sbin/fsck
slink /lib /lib64 |
slink make a symbolic link.
| Code: | | file /lib64/ld-linux-x86-64.so.2 /lib64/ld-linux-x86-64.so.2 755 0 0 |
Copies the input file to the output file (in the intrd) and gives it 755 permissions, thats rwxr-xr-x
The order of file statements is not important. They are copied to the initrd,
There is no need to list any file more than once.
My directory structure is for a /no-multilib/ profile. Multilib may be different.
I just copied the output of

Changed to nod entries: | Code: |
# we have a static /dev so we need all dev entries too
# e.g. /dev/console below
nod /dev/console 0600 0 0 c 5 1
nod /dev/null 0666 0 0 c 1 5
# dev/nvme0 and partitions
nod /dev/nvme0 0660 0 0 b 259 0
nod /dev/nvme0n1 0660 0 0 b 259 0
nod /dev/nvme0n1p1 0660 0 0 b 259 0
nod /dev/nvme0n1p2 0660 0 0 b 259 0
# all the lvm nodes I need
nod /dev/dm-0 0660 0 0 b 259 0
nod /dev/dm-1 0660 0 0 b 259 0
nod /dev/dm-2 0660 0 0 b 259 0
nod /dev/dm-3 0660 0 0 b 259 0 |
I assumed the lvm nodes and nvme0 partition are also "0660 0 0 b 259 0"

After putting the initramfs_list and init in post above, in /root/initrd/
And rebooting, i was greeted with kernel panic. Not able to mount root filesystem.
Think i have to look deeper at how the initramfs_list and init should actually should look. And keep it simple 
[edit] looking at that initramfs_list and init at the wiki, it seems way too complicated. And i lack the skills for every achieving something like that.
That leaves me to a question that is popping up right now: Should i switch from systemd to openRC, because writing initramfs with /dev/tmpfs would probably be easier to achieve on openRC?
But then again, will openRC ever reach end of life status?
Maybe i should keep this system in tact, and use genkernel initramfs. |

Don't want to necrobump my own post. But just want to update, that i switched systemd for openRC, and the custom initramfs works just fine on openRC.
So the custom initramfs failing to mount /home and swap, must have been udev / systemd related. |
