Yes (No??? ), it doesn't work on my chimaera installation. The OP referenced Debian unstable, so it probably hasn't worked its way down yet. If it does work its way down.

Unfortunately, I don't have a daedalus installation to try it on, but it does work on ceres.

With Daedalus (descended from Bookworm) it is available.

deb http://deb.devuan.org/merged daedalus main non-free contrib non-free-firmware

Nala works well with it:

nala update && nala upgrade && nala clean && nala autopurge && nala autoremove

Everything looks good.

W: Skipping acquire of configured file 'non-free-firmware/binary-amd64/Packages'
 as repository 'http://deb.devuan.org/merged chimaera InRelease'
 doesn't have the component 'non-free-firmware'
 (component misspelt in sources.list?)

Edit: reset since code is too stupid to wrap lines to the page

deb http://deb.devuan.org/merged ceres main contrib non-free non-free-firmware

I just added that to my ceres ... unstable sources.list.

After doing so, I had 8 updates to items that would normally be upgraded without that item in the sources.list.

So, on my end, it appears that it should be added to the sources.list.

Debian apparently now recommends users who already have non-free and/or contrib in their sources to add the non-free-firmware entry to ensure that future access to non-free software continues:

deb http://deb.debian.org/debian/ unstable main contrib non-free non-free-firmware

Do I have to do the same for the Devuan-sources-list?

deb http://deb.devuan.org/merged ceres main contrib non-free

Devuan recommends using the actual release names rather than the generic release names.

deb http://deb.debian.org/debian/ unstable main contrib non-free non-free-firmware

Do I have to do the same for the Devuan-sources-list?
