et

Eternal Terminal: a remote shell that automatically reconnects without interrupting the session.

This sysext includes both the client (et) and the server (etserver). The server is not started by default.

How to run the server

• Install the sysext
• Copy the default config:

  $ sudo cp -a /usr/etc/et.cfg /etc/
  

• Start the server now and on boot:

  $ sudo mkdir -p /etc/systemd/system/multi-user.target.d
  $ cat <<EOF | sudo tee /etc/systemd/system/multi-user.target.d/20-et.conf
  [Unit]
  Upholds=et.service
  EOF
  $ sudo systemctl daemon-reload
  

Compatibility

This sysext is compatible with all Fedora variants (CoreOS, Atomic Desktops, etc.).

Versions available

See the et versions.

Usage instructions

First time setup

Run those commands if you have not yet installed any sysext on your system:

sudo install -d -m 0755 -o 0 -g 0 "/var/lib/extensions" "/var/lib/extensions.d"
sudo restorecon -RFv "/var/lib/extensions" "/var/lib/extensions.d"
sudo systemctl enable --now systemd-sysext.service

Installation

Define a helper function:

install_sysext() {
  SYSEXT="${1}"
  URL="https://extensions.fcos.fr/fedora"
  sudo install -d -m 0755 -o 0 -g 0 "/etc/sysupdate.${SYSEXT}.d"
  sudo restorecon -RFv "/etc/sysupdate.${SYSEXT}.d"
  curl --silent --fail --location "${URL}/${SYSEXT}.conf" \
    | sudo tee "/etc/sysupdate.${SYSEXT}.d/${SYSEXT}.conf"
  sudo /usr/lib/systemd/systemd-sysupdate update --component "${SYSEXT}"
}

Install the sysext:

install_sysext et

Reboot your system or refresh the merged sysexts:

sudo systemctl restart systemd-sysext.service
systemd-sysext status

Note that this will merge all installed sysexts unconditionally.

Updates

Update this sysext using:

sudo /usr/lib/systemd/systemd-sysupdate update --component et

If you want to use the new version immediately, make sure to refresh the merged sysexts:

sudo systemctl restart systemd-sysext.service
systemd-sysext status

To update all sysexts on a system:

for c in $(/usr/lib/systemd/systemd-sysupdate components --json=short | jq --raw-output '.components[]'); do
    sudo /usr/lib/systemd/systemd-sysupdate update --component "${c}"
done

Uninstall

Define a helper function:

uninstall_sysext() {
  SYSEXT="${1}"
  sudo rm -i "/var/lib/extensions/${SYSEXT}.raw"
  sudo rm -i "/var/lib/extensions.d/${SYSEXT}-"*".raw"
  sudo rm -i "/etc/sysupdate.${SYSEXT}.d/${SYSEXT}.conf"
  sudo rmdir "/etc/sysupdate.${SYSEXT}.d/"
}

Uninstall the sysext:

uninstall_sysext et

Reboot your system or refresh the merged sysexts:

sudo systemctl restart systemd-sysext.service
