Hello Michael,

well, contrary to your expectation, shipping the compressed linux-firmware leads to an way too big update:

$ cat ./install/packages/meta-core-upgrade-166
Name: core-upgrade
Summary: IPFire Core Update
ProgVersion: 2.27
Release: 166
Size: 299315200
Dependencies: 
File: core-upgrade-2.27-166.ipfire
Services: 
$ ls -lah ./install/packages/core-upgrade-2.27-166.ipfire
-rw-r--r-- 1 root root 286M 24. Mar 10:43 ./install/packages/core-upgrade-2.27-166.ipfire

I do not have the figure ready how much of that 286 MByte are caused by linux-firmware, but
it has to be way more than 100 MBytes. Otherwise, Core 166 would have been to big already, which
I doubt when looking at the currently included filelists.

Thanks, and best regards,
Peter Müller
