Linux distros changed /var/run and /var/lock to reside on an tmpfs in
/run a long time ago, and buildroot seems to agree by providing this
tmpfs on all supported init systems.
Packages on the other hand are currently free to either use /var/run
or /run, and similarly using /var/lock should be identical to the
replacement /run/lock.
This series aims to ensure that *if* /var/lock is needed, then
it will be a symlink to /run/lock. Allowing packages to continue
working and allowing them to migrate to using /run/lock.
If all relevant packages are fixed,
the compatibility symlinks in /var can be dropped.
Status before this patch:
* Systemd
/run will be mounted by PID1, /var/run will be recreated by
/usr/lib/tmpfiles.d/var.conf.
Creating /run/lock/subsys and the compatibility symlink is handled
in /usr/lib/tmpfiles.d/legacy.conf.
But this is *currently not installed* by Buildroot, see [1].
* OpenRC
Seems to check for existence of a /run directory and does all
necessary setup.
* SysV
/var/lock is currently a symlink to /tmp.
* Busybox
Same as sysv (Buildroot uses the sysv skeleton)
Note that we create /run/lock/subsys, so sysv scrips could expect this
directory to exist. Apart from simplifying scripts, creating the dir
early as root adds some security.

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