Burning ISOs

Burning an image to a CD or DVD

On systems that ship cdrtools (e.g., Gentoo, openSuSe, NetBSD, Slackware), you can use cdrecord to write an image to a disc. For example:

cdrecord -v speed=4 alpine-standard-3.8.0-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=4 alpine-standard-3.8.0-x86.iso

Alpine, like Debian, has cdrskin, which can be invoked just like cdrecord above.

Copying an installation image to a USB key

• Arch Wiki on Copying Install ISOs to a USB key, though note that mkarchiso generates hybrid ISOs, whereas as far as I know, alpine-iso does not

Creating an image from a CD

To do the converse operation, copying a CD to an ISO image, just do:

dd if=/dev/cdrom of=/path/to/cdimage.iso

Mounting an ISO image

To mount an ISO without physically burning it to a CD:

modprobe loop LOOP=`losetup -f` losetup $LOOP /path/to/cdimage.iso mount -t iso9660 -o ro $LOOP /mnt ... # when finished umount /mnt losetup -d $LOOP # this step may happen automatically when you umount

or see Arch Wiki on fuseiso.
