unbrot 1f17ef5c2f Update install.md: download script before running with sudo

Process substitution does not survive sudo, so the script must be
downloaded to a temp file first.

OEMDRV Bootstrap — install.sh

the script ./system_setup/install.sh prepares a target machine for automated Fedora deployment. It shrinks an existing partition to carve out a dedicated OEMDRV partition, which Anaconda/Kickstart will detect automatically during installation.

What it does

Lists all ext4 and btrfs partitions that have enough free space to be shrunk.
Asks you to select one and shrinks it by 4 GiB.
Creates a new 4 GiB BTRFS partition labeled OEMDRV in the freed space.
Mounts it to /opt/sys_config with compress=zstd:6.
Clones this repository (depth 1) into /opt/sys_config.

Prerequisites

Run as root on the target machine (live system or installed OS).
The following tools must be present: parted, e2fsck, resize2fs or btrfs-progs, mkfs.btrfs, git, curl.
The partition you want to shrink must not be the root filesystem (/) and must have at least 4.5 GiB free.
Network access to gitea.dtext.online.

Run directly from the repository

Download the script first, then run it as root:

curl -fsSL https://gitea.dtext.online/obel1x/fedora-OEMDRV/raw/branch/main/system_setup/install.sh -o /tmp/install.sh
sudo bash /tmp/install.sh

After the script completes

Configure your environment before running any installation:

cp /opt/sys_config/config/setup_system.conf.dist /opt/sys_config/config/setup_system.conf
# Edit setup_system.conf — set TLDOMAIN, SERVERFQDN_IPA, SERVERFQDN_NC, and paths.

Optionally add local per-machine overrides in config.d/:

# Example: use the devel branch on this machine
echo 'export UPGRADEBRANCH="devel"' > /opt/sys_config/config.d/system_defines.conf

Once configured, boot the Fedora installer from USB — Anaconda will detect the OEMDRV partition and run the Kickstart automatically.

Supported filesystems for shrinking

Filesystem	Method
ext4	`e2fsck` + `resize2fs` (offline)
btrfs	`btrfs filesystem resize` (temporary mount)
