No, please don't make this a split package. You need them both at the same time, there's no reason to make a split package with a single file in each. > the sources to install the modules to /lib/modules/kernelversion/updates This is wrong. updates/ are for... updates.

Yes they have precedence, but for the same reason as above you should not be installing things here. Additionally, you must adhere to the path that the module dictates for its firmware. radeon, for example, expects firmware under radeon/. You can see exactly what it expects with modinfo, e.g. $ modinfo -k 3.3.4-1-ARCH -F firmware radeon | sed 3q radeon/R520_cp.bin radeon/RS600_cp.bin radeon/RS690_cp.bin So in this case, firmware is looked for in each of these base paths (in order): /usr/lib/firmware/updates/$(uname -r) /usr/lib/firmware/updates/ /lib/firmware/updates/$(uname -r) /lib/firmware/updates /usr/lib/firmware/$(uname -r) /usr/lib/firmware /lib/firmware/$(uname -r) /lib/firmware The search stops as soon as udev finds a match. > - Is "depmod -a" after install, upgrade and removal the right approach > to rebuild the module dependencies? No, this is overkill. You should know exactly what kernel you're building against so only run depmod for that one kernel. d
