[arch-general] pacman -Syu -- Applying kernel sysctl settings... Not setting ... Worry?

[Daan De Meyer]

I fixed a bug in systemd where its binaries would output to the journal
instead of stdout when invoked as a child process by pacman. This output
was always there, you just didn't see it until now because it went to the
journal instead of stdout. I get the same messages so I wouldn't worry
about it.

Cheers,

Daan
