journald will always have a runtime log in /run/systemd/journal, and a persistent one in /var/log/journal under certain conditions. By default it will check for the existence of that directory. When /var is not backed by mass-storage you typically don't want your log duplicated and journald should be tuned to account for having only RAM available. With this commit, the directory will no longer be created automatically, but instead it's created only if the root filesystem is writeable. It is rather easy for users to opt-in by either creating that directory (e.g. with a tmpfiles fragment) or editing /etc/systemd/journald.conf.

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.
