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.
