We 'fix' it from system-wide vps.mount
The part that does the fix:
*****
if [[ "${OSTEMPLATE}" =~ "centos-7" && -n "${HOSTNAME}" ]]; then
echo "OVZHOSTNAME=\"${HOSTNAME}\"" > ${VE_ROOT}/etc/sysconfig/ovzhostname
if [[ ! -f ${VE_ROOT}/etc/systemd/system/ovzhostname.service ]]; then
cat << XXTAGXX > ${VE_ROOT}/etc/systemd/system/ovzhostname.service
[Unit]
Description=hostname fix for cpanel
After=network.target
Before=cpanel.service
[Service]
Type=oneshot
ExecStart=/etc/init.d/ovzhostname
[Install]
WantedBy=multi-user.target
XXTAGXX
fi
if [[ ! -L
${VE_ROOT}/etc/systemd/system/multi-user.target.wants/ovzhostname.service ]];
then
ln -s /etc/systemd/system/ovzhostname.service \
${VE_ROOT}/etc/systemd/system/multi-user.target.wants/ovzhostname.service
fi
if [[ ! -f ${VE_ROOT}/etc/init.d/ovzhostname ]]; then
cat << XXTAGXX > ${VE_ROOT}/etc/init.d/ovzhostname
#!/bin/bash
OVZHOSTNAME=""
if [[ -f /etc/sysconfig/ovzhostname ]]; then
source /etc/sysconfig/ovzhostname
if [[ -n "\${OVZHOSTNAME}" ]]; then
echo "\${OVZHOSTNAME}" > /etc/hostname
hostname "\${OVZHOSTNAME}"
hostnamectl set-hostname "\${OVZHOSTNAME}"
fi
fi
XXTAGXX
chmod 0755 ${VE_ROOT}/etc/init.d/ovzhostname
fi
fi
