[Fedora-livecd-list] Are these error messages serious?

[Ranjan Maitra]

Hello, 

I created a livecd disk using a kickstart file which I modified from
the LXDE spin and got these error messages (at different points of the
ISO creation):

I wonder if any of these messages are serious. In any case, is there an
easy way to get rid of them?

Many thanks,
Ranjan

retrying (1/3)... The unit files have no [Install] section. They are
not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another
unit's .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which
has a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path,
timer, D-Bus, udev, scripted systemctl call, ...).
