Machines with static IP installing CentOS, Alma, Rocky, Fedora, Ubuntu must include the parameter --ci.
If it is uncertain whether the machine has a static or dynamic IP, you can also add the parameter --ci.

bash reinstall.sh centos   7|8|9  (8|9 for the stream version)
                  alma     8|9
                  rocky    8|9
                  fedora   38|39
                  debian   10|11|12

--ci              Force the use of the cloud image

Feature 2: DD

Supports gzip, xz formats.
For machines with static IP, DD Windows, and the script will automatically configure the IP.

bash reinstall.sh dd --img https://example.com/xxx.xz

Feature 3: Reboot to Alpine Rescue System (Live OS)

Can be connected via SSH to perform manual DD, modify partitions, manually install Arch / Gentoo, etc.
If the disk content is not modified, rebooting again will return to the original system.

bash reinstall.sh alpine --hold=1

Feature 4: Reboot to netboot.xyz

Can install more systems using web panel VNC.
If the disk content is not modified, rebooting again will return to the original system.

bash reinstall.sh netboot.xyz

Feature 5: Install Windows ISO
