Install zfs on Rocky Linux

Submitted by gill on Sat, 09/02/2023 - 12:18

From a fresh Rocky Linux install, need to add some repos.

# dnf install epel-release -y

https://docs.rockylinux.org/books/lxd_server/01-install/

Install the repo instructions for getting zfs

dnf install https://zfsonlinux.org/epel/zfs-release-2-2$(rpm --eval "%{dist}").noarch.rpm

Installing zfs pulls in all the kernel modding requirements like kernel-devel and gcc

dnf install zfs

Load the zfs module

/sbin/modprobe zfs

After installing Fedora, here are some things to add.

Edit /etc/dnf/dnf.conf and add the following lines:

max_parallel_downloads=10
fastestmirror=true
deltarpm=true

Then run the dnf upgrade:

sudo dnf -y upgrade --refresh

Reboot after refreshing.

Update the firmware

sudo fwupdmgr get-devices
sudo fwupdmgr refresh --force
sudo fwupdmgr get-updates
sudo fwupdmgr update

Fedora kiosk

Install gnome kiosk (gdm, zenity, and firefox should already be installed).

sudo dnf install -y gnome-kiosk-script-session

Create the user and give them a password.

sudo useradd -c "TV user" -m tvuser

sudo passwd tvuser

Modify the GDM configuration to automatically login the user on startup. Edit /etc/gdm/custom.conf to add these:

[daemon]
AutomaticLoginEnable=True
AutomaticLogin=tvuser

Manage podman with systemd

Submitted by gill on Tue, 01/03/2023 - 17:42

After getting the containers running you can have systemd start and stop them for you.

$ podman pull docker.io/library/httpd

$ podman run -dt -p 8080:80/tcp --name httpd docker.io/library/httpd

Now you can create systemd files:

$ cd $HOME/.config/systemd/user

$ podman generate systemd --new --files --name httpd

The podman generate command creates a systemd service file named container-httpd.service. Reload the daemon to read the new file:

$ systemctl --user daemon-reload

Stop the running container

Permanently enable wake-on-lan with nmcli

Submitted by gill on Sat, 07/23/2022 - 10:41

First, check that the interface supports WoL:

sudo ethtool enp4s0 |grep Wake
    Supports Wake-on: g
    Wake-on: d

Supports Wake-on: g is required for WoL to work. You can change the setting with ethtool or NetworkManager. When you use ethtool, the change does not survive a reboot.

sudo ethtool -s enp4s0 wol g

By using Network Manager nmcli commands, the change persists reboots.
