In the end, FHANDLE needs to be selected in the Linux configuration
for systemd to work properly.
This option is enabled automatically when systemd is selected as init
system in BR. In Thomas case (and mine too), the kernel was too old
and it was not build with this feature enabled.
Rebuilding fixed the issue.
