Currently, makedevs will query the host's /etc/passwd and /etc/group to resolve usernames and group names. This is inherently flawed, as we can never guarantee that the UIDs will be the same on the target as on the host, or even whether a particular user does exist on the host. This is because getpwnam() and getgrnam() will forcibly read the system's /etc/passwd and /etc/group, and there is no way to tell them to look anywhere else. However, we can use fgetpwent() and fgetgrent() instead, for which we can pass a FILE* stream to read from to get the entries. This means we must implement the scanning-loop ourselves, but fortunately, that's pretty trivial to do.

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.
