Commit 8089cefed8 ("systemd: Add
PACKAGECONFIG for sysvinit") decoupled enabling of systemd's sysvinit
handling behavior behind a distinct PACKAGECONFIG feature.
This new option affects among other things the installing of
tmpfiles.d/legacy.conf, which is responsible for creating /run/lock
directory, which is pointed to by /var/lock symlink provided by
base-files package.
In case the option is not enabled, then base-files provided /var/lock
is a dangling symlink on resulting rootfs, causing problems with
certain Linux userspace components that rely on existence of writable
/var/lock directory. As an example:
# fw_printenv
Error opening lock file /var/lock/fw_printenv.lock
Since Filesystem Hierarchy Standard Version 3.0 states in
https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch05s09.html that
Lock files should be stored within the /var/lock directory structure.
Ensure the /run/lock directory is always created, so that lock files
can be stored under /var/lock also when 'sysvinit' handling is
disabled.

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.
