As reported by Thierry Bultel [1], dracut doesn't work since the
version bump to version 059.
Further investigation by Andreas Naumann [2] reported that the issue
come from this commit d010fa0 refactor(dracut-install): fork() instead
of popen(), sanitise line reading [3].
The issue come from our dracut_wrapper and how DRACUT_LDD is defined.
Indeed dracut expect DRACUT_LDD=ldd or a single binary (without
arguments) but we are using "prelink-rtld --root='${sysroot}'".
With the change introduced by [3], our DRACUT_LDD is used
directly by execlp() leading to an error:
execlp(ldd, ldd, fullsrcpath, (char *)NULL);
Use mktemp to generate a temporary dracut-ldd script using
prelink-rtld --root='${sysroot}' ${1}
execute dracut.real in a subshell to cleanup the temporary file
at the end of the dracut wrapper script.

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
