I'm shy now that I know other people can automatically see this one.
But it must be done, for science (and proposal writing)

#!/bin/bash
yum -y install httpd
systemctl enable httpd
systemctl start httpd
hostname > /var/www/html/index.html

# This is the network config written by 'subiquity'
network:
  ethernets:
    enp0s3:
      dhcp4: yes
      nameservers:
          addresses: [8.8.8.8,8.8.4.4]
  version: 2

in case of SCCM error 0x800700A1 do the following:

diskpart
list disk                (list all disks on system)
select disk 0            (0 being the disk to setup)
clean                    (wipes the disk)
create partition primary (creates windows partition)
select partition 1       (selects the first partition)
format quick fs=NTFS     (sets format of primary partition)
assign letter C          (assigns the drive letter to "C")
exit                     (exits diskpart)
