This issue exists since the initial commit that enabled parallel start=20
of rc scripts. I do not see why the X server does not start, since the
commands that are started in parallel appear to be completely unrelated
and I do assume that scripts are only started from the next line after
the previous ones are running (but maybe not yet completely functional).

SDDM is in the 2nd-last line of rcorder -p output on my system:

	/etc/rc.d/sendmail
	/usr/local/etc/rc.d/apache24
	/usr/local/etc/rc.d/postfix
	/etc/rc.d/othermta
	/etc/rc.d/bgfsck
	/usr/local/etc/rc.d/postgresql
	/etc/rc.d/securelevel
	/usr/local/etc/rc.d/sddm

(All the above listed rc files are on a single line, actually.)


BTW: I was surprised to see the following line 139 in /etc/rc:

files=3D`rcorder ${skip} ${skip_firstboot} /etc/rc.d/* ${local_rc}=20
${_rc_parallel} 2>/dev/null`


Since ${_rc_parallel} is at the end of the command line, it does not
have any impact on the output that is generated ...

This seems to indicate that scripts from /usr/local/etc/rc.d are not
executed in parallel, which makes the SDDM failure even more
surprising.
