This is a selection of settings and preferences for my Fedora Silverblue installation.

2. Boot the ISO and stop at Grub screen
3. Highlight "Install Fedora", press e and append:

inst.ks=https://raw.githubusercontent.com/francoism90/dotfiles/main/silverblue.ks

or when using an USB-device labelled LIVE:

inst.ks=hd:LABEL=LIVE:ks/silverblue.ks

4. Press F10 to start the installation using the kickstart file

Maintenance

Reference:

• https://rpmfusion.org/Howto/OSTree
• https://docs.fedoraproject.org/en-US/fedora-silverblue/troubleshooting/

To show difference after upgrades:

rpm-ostree db diff -c

nofile

Increasing nofile limits may be needed for certain applications and games to work.

See https://access.redhat.com/solutions/1257953 for more details.

NOTE: Reboot the system to apply increased limits.

Filesystem

Trim

Enable the fstrim timer:

sudo systemctl enable fstrim.timer --now

Encryption

If you are using encryption on a NVMe/SSD, you may want to improve performance by disabling the workqueue.

See https://wiki.archlinux.org/title/Dm-crypt/Specialties#Disable_workqueue_for_increased_solid_state_drive_(SSD)_performance for details.

Btrfs

If you are using Btrfs, you may want to use https://github.com/kdave/btrfsmaintenance:

rpm-ostree install btrfsmaintenance
nano /etc/sysconfig/btrfsmaintenance

Enable the timers:

sudo systemctl enable btrfs-balance.timer btrfs-defrag.timer btrfs-scrub.timer btrfs-trim.timer --now

Software

Toolbox

It is discourage to install (large) software on the ostree. Try to use Flatpaks and toolboxes (toolbox create and toolbox enter) as much as possible.

You can pull the latest toolbox, using:

podman pull fedora-toolbox:41

To update a toolbox:

toolbox enter
sudo dnf update && sudo dnf upgrade

You can create multiple toolboxes, and even manage them using Podman Desktop.

Firefox

To replace the provided default Firefox package, with the Firefox Flathub version for example:

rpm-ostree override remove firefox firefox-langpacks

NOTE: You can also hide the desktop entry itself.

Brave

Depending on your hardware, you may need to enable/disable different flags. See https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/gpu/vaapi.md#vaapi-on-linux for details.

Podman

Enable and use rootless containers:
