Paradigm for customising operating systems
Just enough operating system
(
JeOS
, pronounced "juice" according to
SUSE
) is a paradigm for customizing
operating systems
to fit the needs of a particular application such as for a
software appliance
. The platform only includes the operating system components required to support a particular application and any other third-party components contained in the appliance (e.g., the
kernel
). This makes the appliance smaller, faster (to boot and to execute the particular application) and potentially more secure than an application running under a full general-purpose OS.
Common implementations

Typically, a JeOS will consist of the following:
- JeOS media (OS core [kernel, virtual drives, login])
- OS minimum maintenance tools
- Minimum user space tools
- Packages repository (DVD or network based)
It is important to differentiate between true fully
minimalized OS
install profiles forced, for example, with security hardening tools or representing Recovery Console images and
JeOS
richer install profiles which are designed and built for wider audience usage, so
VM
/
VA
creators and their users can easily perform needed installation or configuration tasks.
