On other distros like ubuntu/centos, libnss-db usually provides: - The libraries - The Makefile to create database (in /var/db for centos, /var/lib/misc/ for ubuntu) - The makedb command (it's in glibc-common for centos7) What we had is: - The libraries are in glibc-extra-nss - The Makefile is removed - The makedb command is in glibc-utils (lack of dependency) So when glibc-extra-nss is installed but glibc-utils is not, we see error like: nscd[165]: 165 checking for monitored file `/var/db/group.db': No such file or directory nscd[165]: 165 checking for monitored file `/var/db/passwd.db': No such file or directory And there is not an easy way to create these databases. To fix the issue: - Re-package the libraries into libnss-db - Don't remove the Makefile and add it in libnss-db - Add RDEPENDS for libnss-db on glibc-utils - Provide a shell script, makedbs.sh, to generate the db files. This is to avoid dependency on 'make'. Notes: 1. For external toolchain, an extra package 'libnss-db' need to be provided If replacing glibc from core. 2. I've check the git history of nss/db-Makefile, the last two functionality fix is as below. - fix non-portable `echo -n` usage -- Date: Thu Aug 6 04:14:20 2015 -0400 - Fix db makefile rule for group.db -- Date: Fri Nov 11 14:43:36 2011 +0100 So I think this file is stable enough. And using makedbs.sh which is crafted according to that file is not likely to cause maintanence problem.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
