On systems that ship cdrtools (e.g., Gentoo, openSuSe, NetBSD, Slackware), you can use <code>cdrecord</code> to write an image to a disc. For example:
Many systems provide the <code>cdrecord</code> command (on Alpine it is provided by the {{pkg|cdrkit|arch=}} package) to write an image to a disc. For example:

<pre>cdrecord -v speed=4 alpine-standard-3.8.0-x86.iso</pre>


If there's only one CD drive on the system, it should be auto-detected. If not, find the device name using <code>lsblk</code> and specify the <code>dev</code> option. For example:

Alpine, like Debian, has <code>cdrskin</code>, which can be invoked just like <code>cdrecord</code> above.

Burning an image to a CD or DVD

Many systems provide the cdrecord command (on Alpine it is provided by the cdrkit package) to write an image to a disc. For example:

cdrecord -v speed=0 alpine-standard-3.20.3-x86.iso

If there's only one CD drive on the system, it should be auto-detected. If not, find the device name using lsblk and specify the dev option. For example:

cdrecord -v dev=/dev/sr0 speed=0 alpine-standard-3.20.3-x86.iso
