I dont like initrd / initramfs (better: I hate it).
I read this Mail from Helen Koike and with her beginnig I completly agree:
| Quote: | As mentioned in previous discussions, the need to create an initramfs adds
another layer of complexity when performing tests or preparing a BSP for
a board.
Taking care of initramfs is always a bit painful, it also occupies space and is
another level of complexity in the stack.
A practical example as mentioned by Kees is that Chrome OS has a limited amount
of storage available for the boot image as it is covered by the static root of
trust signature.
This feature is already used by Android and Chrome OS in devices already shipped
to the market/end-users. |
from https://www.redhat.com/archives/dm-devel/2019-February/msg00108.html
But I didnt found much when I googled "dm-mod.create".
So, does anybody has useful infos about (or links) ?

I don't like initrd's either so i think it's a nice feature.
I haven't tested it, but i will as soon as a kernel with this feature is stable in portage. I have a few systems with encrypted root devices and they have initrd's just for that reason.
I checked at https://www.kernel.org/ and i see it's merged into the linux-next, 5.6-rc5, 5.5.9 and 5.4.25 kernels. You'll need to enable the CONFIG_DM_INIT option to be able use it.
