I am wondering if it's possible to remove unneeded firmware from fedora. Currently this is installed:

$ sudo dnf list atmel-firmware.noarch ipw2100-firmware.noarch ipw2200-firmware.noarch iwl100-firmware.noarch iwl1000-firmware.noarch iwl105-firmware.noarch iwl135-firmware.noarch iwl2000-firmware.noarch iwl2030-firmware.noarch iwl3160-firmware.noarch iwl3945-firmware.noarch iwl4965-firmware.noarch iwl5000-firmware.noarch iwl5150-firmware.noarch iwl6000-firmware.noarch iwl6000g2a-firmware.noarch iwl6000g2b-firmware.noarch iwl6050-firmware.noarch iwl7260-firmware.noarch libertas-usb8388-firmware.noarch linux-firmware.noarch zd1211-firmware.noarch installed | grep firmware 1.3-18.fc28 @fedora

Since my network card is Centrino Advanced-N 6205 using something like firmware=18.168.6.1 is it save to remove the rest? and even more - so in the end I could only stick to iwl6000g2a-firmware.noarch or iwl6000g2b-firmware.noarch- according to https://fedoraproject.org/wiki/Firmwa... ?

Thanks for help

First download all rpm, just to be safe, in case of not working wifi.

sudo dnf download $(sudo dnf list installed | grep firmware | grep iw)

Remove all, except for your version

lshw -C Network

sudo dnf remove $(sudo dnf list installed | grep firmware | grep iw | grep -v 18.168.6.1)

So I could reduce it from 16 to 6 firmware packages. From the fedora firmware wiki I suppose it's ether firmware iwl6000g2a-firmware.noarch or iwl6000g2b-firmware.noarch - so I just tried to remove and active both, with reboots in between, and in the end I had a working wifi with only iwl6000g2a-firmware.noarch.

Later I also removed all the other wifi firmwares, to end with:

sudo dnf list installed | grep firmware

iwl6000g2a-firmware.noarch 18.168.6.1-83.fc28.1 @@commandline
linux-firmware.noarch 20180402-83.git8c1e439c.fc28

Use dmesg to confirm what is being used/loaded on your system.

root  /  dmesg | grep firmware
[    0.035933] Spectre V2 : Enabling Restricted Speculation for firmware calls
[    9.346528] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq

Double-check the package name(s) you need to keep

 root  /  rpm -qf /usr/lib/firmware/intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq 
linux-firmware-20180525-85.git7518922b.fc29.noarch

Protect these packages

root  /  rpm --qf "%{NAME}\n" -qf /usr/lib/firmware/intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq >> /etc/dnf/protected.d/firmware.conf

Remove unneeded firmware

dnf list installed |grep firmware |grep -v linux-firmware | awk '{print $1}' | xargs dnf remove -y

These packages are fairly small, except for linux-firmware. The package linux-firmware should be kept as that one contains firmware for the CPU, For the rest, I couldn't tell which one is actually needed, but for the small size it might not even be worth it to remove any of them.

Sure, the packages are quite small but I don't want to have packages on my system that I don't need and I have a bad internet connection, so every package I don't have to download is a blessing :P
