In eudev and systemd, we have code that deletes the hwdb sources from the target - they are not useful since a binary hwdb is created from them. However, if eudev or systemd is not used, then those sources are not useful either. It's possible that other packages than eudev or systemd install hwdb files, which would be left on the system. Always remove the hwdb files. Note that we don't expect much space savings from this, but anything may help. It's certainly more consistent to do it always than just in eudev and systemd. We do this both from /usr/lib/udev (usual installation path for systemd) and in /etc/udev (usual installation path for eudev) because packages may install in either location. We keep the comment explaining why it's done in rootfs-pre-cmd instead of target-finalize - this was only present in eudev.mk.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
