Hi!
Since version 215, systemd installs a unit file to run /sbin/ldconfig when
starting the target. Building a target image with systemd implies using a
glibc-based toolchain. But when doing so, ldconfig is not installed on the
target, which causes the unit to fail (the system is usable, though).
On the other hand, when building a target image with uClibc, ldconfig is
installed.
Is it a bug or a feature? Am I missing something?
Best regards,
ELB

The ldconfig handling needs love. We even try to run ldconfig on the
build machine at the end of the build, and we have a very old patch
sitting about this: http://patchwork.ozlabs.org/patch/255486/.
Someone needs to look which C library needs ldconfig, and which
doesn't, and take actions to clean this up.
Best regards,
Thomas
