Hi.
I want to use btrfs as root, on standard Debian I use update-initramfs and use initrd with modules, is possible to add the module btrfs and boot with btrfs root on Osmc? I know osmc don’t support standard method of initramfs-tools
You would need to build a custom initramfs and build it for each kernel update

Yes, I know, but I don’t know how to generate it on osmc, the standard Debian way don’t work
vim /etc/initramfs-tools/modules
update-initramfs -cv -k all
You would need to build and embed it with the kernel.
in theory on Pi the Debian initramfs could probably be used if you customised config.txt, but I have not tried it.

All Debian based distro use the method of initramfs described, i don’t understand why is not supported on osmc. With this method if you need a module before boot (fs are usually the main “example” but there are also some other modules needed) you simply add the module on initrd (/etc/initramfs-tools/modules) and rebuild it (update-initramfs -uv or -cv).
Otherwise you must rebuild the entire kernel and include statically the module!
No – all Debian distros do not support this.
OSMC is an embedded system.
You can install initramfs-tools and build a custom initramfs if you wish to do so. I think you would only lose the early splash screen and recovery options.

Works fine, very strange why return me an error in first time I had ran it.
Did you update config.txt to use it?

Just to said..
works mean works starting but with ext4 on root 
I said “works” because the os boot, and don’t return errors, but if I use the btrfs fs as root fs, give errors (the script on boot require an ext4 fs)
