-#How to create a fedora 29 based sys-template
+# How to create a fedora 29 based sys-template
+
+This Howto will cover how I build a template which I use for my sys-vms, like:
+
+- sys-net
+- sys-firewall
+- sys-usb
+- sys-vpn
+
+While the default sys-VMs in Qubes work, I like to run my own custom build template which have less packages installed and are based on the fedora-29 minimal template.
+
+You can just copy & paste the following content, which will setup the new template.
+If you have any questions or if you have comments to improve the setup, do not hesitate to contact me.
+
+```
+template=fedora-29-minimal
+systemplate=t-fedora-29-sys
+
+# get fedora-29-minimal template
+sudo qubes-dom0-update qubes-template-$template
+
+#remove old template
+qvm-kill $systemplate
+qvm-remove -f $systemplate
+
+#clone template
+qvm-clone $template $systemplate
+# update template
+qvm-run --auto --user root --pass-io --no-gui $systemplate \
+  'dnf update -y'
+
+# install a missing package for fedora-29-minimal
+# without it, gui-apps will not start
+qvm-run --auto --user root --pass-io --no-gui $systemplate \
+  'dnf install -y e2fsprogs'
+
+# Install required packages for Sys-VMs
+qvm-run --auto --user root --pass-io --no-gui $systemplate \
+  'dnf -y install qubes-core-agent-qrexec qubes-core-agent-systemd \

+  NetworkManager-openvpn NetworkManager-openvpn-gnome \
+  NetworkManager-wwan NetworkManager-wifi network-manager-applet'
+
+# Optional packages you might want to install in the sys-template:
+qvm-run --auto --user root --pass-io --no-gui $systemplate \
+  'dnf -y install nano less pciutils xclip'
+
+# Nice(r) Gnome-Terminal compared to xterm
+qvm-run --auto --user root --pass-io --no-gui $systemplate \
+  'dnf -y install gnome-terminal terminus-fonts dejavu-sans-fonts \
+   dejavu-sans-mono-fonts'
+
+# Set new template as template for sys-vms
+qvm-shutdown --all --wait --timeout 120
