I use dracut, how do I boot from a read-only snapshot.

/usr/lib/dracut/modules.d/ There seems to be some dracut scripts under this path. But I don't know how to add the grub-btrfs-overlayfs script.

[Antynea]

The grub-btrfs-overlayfs script is only written for mkinitcpio.

dracut works differently and requires a specific script to match its mechanisms. I don't have enough knowledge on dracut to do this.

You can try it yourself, or wait for the community to work on it.

I did some porting attempts of dracut, and found that none of the hooks in the document seem to make grub-btrfs-overlayfs take effect. It seems that the initialization process of dracut is somewhat different from that of mkinitcpio, and I don't have any relevant knowledge.
