systemd automatically creates tmpfs mounts for /tmp, /run, /dev/shm, and
others. If tmpfs is not enabled in the kernel, systemd crashes with an
unknown filesystem error on boot. This hasn't manifested itself during
tests with defconfigs such as pc_x86_64_efi_defconfig for a few reasons:
- No defconfig uses systemd as the init system by default
- Even if a user does use pc_x86_64_efi_defconfig and changes to systemd,
the board/pc/linux.config file enables CONFIG_PCI, which selects
CONFIG_TMPFS.
- The systemd init tests use a prebuilt kernel with tmpfs enabled.
Enable tmpfs unconditionally to ensure that systemd always boots, even with
a minimal kernel built.

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.
