The goal of liminalOS is to allow my computing environment to exist in different
|
||||||
|
places (computers) at the same time, without the minor disparities, issues, and
|
||||||
|
inconsistencies that arise from traditional approaches such as scripting. This
|
||||||
|
works exceptionally well, demonstrated by the fact that I have the exact same
|
||||||
|
environment across three separate machines, spanning two completely different
|
||||||
|
CPU architectures.
