On install step the host tool syrepoctl is used to install some YANG modules. Unfortunatly syrepoctl creates some files in /dev/shm folder and does not cleanup afterwards. This files can be incompatible depending on the used sysrepo version. This causes autobuilder failures when updating the package [1]. To make sure we can remove this leftovers of sysrepoctl we specify a build specific SYSREPO_SHM_PREFIX. With this the files can deleted safely after installation is completed. This also ensures that concurrent parallel builds will not affected mutualy. The prfix must be unique between concurrent builds, so we use the build directory ($(CONFIG_DIR)) to discriminate builds. It must also be unique between top-level parallel package builds, so we also use the name of the current package to discriminate.

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.
