Risks to removing udev-hwdb

MichaelBMiner — Wed, 16 Feb 2022 16:12:12 GMT

I have generated an image and have enabled build history. One interesting file I get from this is the installed-package-sizes.txt. It lists all packages installed along with their size in KiB. By far the largest is udev-hwdb.

This can easily be removed by adding

BAD_RECOMMENDATIONS += "udev-hwdb"

to a bb file.

What are the risks to removing this package? This question was asked in a previous question after an answer to the initial question was found.

HWDB is a database of devices for udev diagnostic output.
So I suppose everything should be running fine after udev-hwdb removing except the diagnostic may become unclearю

Would I still be able to insert a USB device and have it enumerate? If I understand correctly the answer is yes, but if there was an error I could not easily find out why.

Is there a way to trim the udev-hwdb so it does not take so much space in my image?
