I rembember there was a discussion about the initrd name and the plan was to have the same name on all distributions, and there's a new option in dracut.conf
*initrdname=*"_<filepattern>_":: Specifies the file name for the generated initramfs if it is not set otherwise. The initrdname configuration option is required to match the _initr*${kernel}*_ file pattern and only one file with this pattern should exists in the directory where initramfs is loaded from. Defaults to _initramfs-${kernel}.img_. But I don't remebmer the details about the change. It seems that dracut uses initramfs... by default but Debian is using initrd... when calling /etc/kernel/postinst.d/dracut So if you still using the kernel postinst hook, things are fine IMO. -- regards Thomas
