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.
