Just enough operating system

Just Enough Operating System (JeOS, pronounced "juice") 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.

gollark: Budgeting etc. for it probably would take more time than editing the code directly.
gollark: Give budget to replace a few lines of code...? Your company is weird.
gollark: I should start a consulting firm and wildly guess about possible issues with people's code!
gollark: This is why you must always trust random people on the internet.
gollark: Interweeb, if you will/
