Abstract
A planned system configuration is stored to a volatile memory coupled to a processor executing a first operating system kernel. The planned system configuration is tagged. A boot of a second operating system kernel is initiated while preserving in the volatile memory contents stored therein, and following the boot of the second operating system kernel, a set of parameters referencing the tagged planned system configuration is retrieved from the volatile memory. The planned system configuration is then used, based on the retrieved set of parameters.
Claims11
A method comprising:
- storing, to a volatile memory coupled to a processor executing a first operating system kernel, a planned system configuration;
- tagging the planned system configuration;
- initiating a boot of a second operating system kernel while preserving in the volatile memory contents stored therein;
- retrieving, following the boot of the second operating system kernel, a set of parameters referencing the tagged planned system configuration from the volatile memory;
- and
- using the planned system configuration, based on the retrieved set of parameters.
