[systemd-devel] known but not-listed units

[Stijn De Weirdt]

hi all,

i'm having following situation on a centos 7.2 system (systemd-219-19.el7)

there is a sysvinit service called netconsole that is not listed as a
unit or unitfile, but the unitfile was generated and systemctl seems to
be able to handle the unit.

the only odd issue is that this service is not enabled (chkconfig shows
all levels as off).
this system has otehr sysvinit services that do show up as units (but
for those, at least one level is on)

is this "normal"? and what sort of units exits that are not listed as
units or unitfiles in general?

i pasted some output below, hope this helps

many thanks,

stijn
