+How to handle CD/DVD burning
+============================
+
+## Install growisofs
+
+  apt install genisoimage
+
+
+## Burn to optical media from ISO
+
+growisofs -dvd-compat -Z /dev/srX=path/to/my.iso
+
+
+## "Burn" to USB from ISO
+
+  dd bs=4M if=path/to/my.iso of=/dev/sdX status=progress oflag=sync
+
+
+## Get checksum of disc
+
+- Use isoinfo (from genisoimage pkg) to get size params.
+- Use dd parameterized by previous output.
+
+  isoinfo -d dev=/dev/srX
+  dd bs=${Logical block size} count=${Volume size} if=/dev/srX | md5sum -b
+
+
+## Get checksum of usb drive
+
+- Use stat to get block/count.
+- Divide num by drive block size (likely 4096).
+- Use dd parameterized by previous output.
+
+  stat -c '%s' my.iso
+  dd bs=${Logical block size} count=${Volume size} if=/dev/sdx | md5sum -b
