From 34105077c777b0d2c5c69f39921f376b84ce1443 Mon Sep 17 00:00:00 2001 From: Philip J Freeman Date: Sat, 31 May 2025 12:34:14 -0700 Subject: Deploying a demo amd64 debian-based OS via ostree This is a prototype outline for building and deploying a debian based OS with ostree. For purposes of demonstration, the OS runs from a bootable USB device on a UEFI capable amd64 machine. Once a USB device is created and booted, the OS can be updated using a simple shell script. --- make_rootfs.sh | 57 --------------------------------------------------------- 1 file changed, 57 deletions(-) delete mode 100755 make_rootfs.sh (limited to 'make_rootfs.sh') diff --git a/make_rootfs.sh b/make_rootfs.sh deleted file mode 100755 index 811c5cb..0000000 --- a/make_rootfs.sh +++ /dev/null @@ -1,57 +0,0 @@ -#!/bin/bash -xe - -IMAGE_VERSION=$( date +%Y%m%d.%H%M%S ) - -function unmount_pseudo_filesystems(){ - set +e - for dir in dev sys proc; do umount -v "$root"/"$dir"; done - set -e -} - -function on_exit(){ - set +e - unmount_pseudo_filesystems - umount -v "$root" -} -trap on_exit EXIT - -root=rootfs/"$IMAGE_VERSION" - -mkdir -p "$root" - -# bootstrap the OS - -debootstrap noble "$root" - -for dir in /proc /sys /dev; do - mount --bind "$dir" "$root"/"$dir" -done - -export DEBIAN_FRONTEND=noninteractive - -chroot "$root" locale-gen en_US.UTF-8 - -chroot "$root" apt-get update - -# Install a kernel and bootloader - -chroot "$root" apt-get -y --no-install-recommends install linux-generic-hwe-24.04 grub-efi - -if [ "$1" == "with-app" ]; then - # Install an application - chroot "$root" apt-get update - chroot "$root" apt-get install -y software-properties-common - chroot "$root" add-apt-repository -y universe - chroot "$root" apt-get update - chroot "$root" apt-get -y install nethack-console -fi - - -# Cleanup - -chroot "$root" apt-get clean - -unmount_pseudo_filesystems - -rm -rf "$root"/dev/* -rm -rf "$root"/var/lib/apt/lists/* -- cgit v1.2.3
