The mdnsd runtime test can randomly fail on slow runners. It's hard to reproduce locally (only one failure after a few attempts) but we can reproduce it easily by removing the while loop entirely. It turns out that mdnsd is started by S50mdnsd before the emulator.login() change the system date: [BRTEST# date -s @1788032864 Sat Aug 29 19:47:44 UTC 2026 Since the minimal rootfs.cpio generated for TestMdnsd doesn't have any ntp client installed, it start with "January 1, 1970". The date change may cause some issue to the mdnsd daemon which blocks any response from mquery command. When the problem occurs, "mquery -T _http._tcp" reply is empty: # mquery -T _http._tcp Querying _http._tcp.local. for PTR (12) ... press Ctrl-C to stop To workaround the issue, restart mdnsd manually.

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 https://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.
