ماذا يفعل

lsinitrd without arguments shows the initramfs of the running kernel: the dracut version and arguments, the dracut modules used, and a file list. With -f FILE it prints one file from the image — useful to check if a config (like /etc/fstab or a modprobe file) is inside.

1Image of the running kernel
```
#lsinitrd | less
```
Header, dracut modules, file list.
2Only the dracut modules
```
#lsinitrd -m
```
lvm, crypt, systemd …
3Is a driver inside?
```
#lsinitrd | grep -E 'virtio_blk|nvme'
```
The root disk driver must be there.
4Show a file from the image
```
#lsinitrd -f /etc/modprobe.d/loop.conf
```
Check that your config is included.
5Image of another kernel
```
#lsinitrd -k 6.12.0-55.el10.x86_64 | head
```
Before you boot that kernel.
6Biggest files
```
#lsinitrd -s | head
```
Why is the image so big?

7Unpack to look around

#mkdir /tmp/ird && cd /tmp/ird && lsinitrd --unpack /boot/initramfs-$(uname -r).img

Full file tree.

8Check LVM names inside

#lsinitrd -f /etc/lvm/lvm.conf | grep -v '^\s*#' | grep -v '^\s*$' | head

After renaming a VG, rebuild with dracut.

9Kernel arguments in the image
```
#lsinitrd | grep -A3 'dracut cmdline'
```
Built-in arguments.
10Early microcode
```
#lsinitrd --unpackearly -v
```
CPU microcode updates load from here.
