The default inittab files added by busybox and sysvinit run 'swapon -a'
during init and 'swapoff -a' during shutdown.
But, the swapon/swapoff programs are not guaranteed to be
available. For the busybox versions, it is steered by
CONFIG_SWAPON/CONFIG_SWAPOFF. For the util-linux versions, it is steered by
BR2_PACKAGE_UTIL_LINUX_BINARIES.
In a case where swapon/swapoff is not available but the inittab tries to
execute them, the boot log would be polluted by error messages like:
swapon: not found
Avoid this by commenting out the swapon/swapoff lines if the swapon/swapoff
binaries are not available.

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 Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
