quotatab — Descriptions of devices with disk quotas
The quotatab file lists human descriptions of devices for the purpose of warnquota(8) notifications.
Each line consists of a device path name followed by a colon and a description. White space, apostrophe, and double quote characters surrounding the names and descriptions will be stripped. The description field can encode a new-line as a pipe character.
Empty lines or lines starting with a hash sign or a semicolon are ignored.
/dev/sda2: Home directories.|This becomes the second line.
