Abstract

Methods, apparatuses, and systems for distribution of software updates are described. A file representing a difference between a first software stack and a second software stack and a task sequence may be received at a computer. The task sequence may represent instructions for installing the second software stack on the computer using the file and a stored image that represents the first software stack. The computer then may execute the task sequence to use the file and the stored image to install the second software stack on the computer. In one example, a second file representing a difference between the first software stack and a third software stack may be received by the computer, and the task sequence may include further instructions for installing the second software stack based on the first file, the second file, and the stored image.

Claims

1. A method comprising:

receiving, at a computer, a file representing a difference between a first software stack and a second software stack;

receiving, at the computer, a task sequence representing instructions for installing the second software stack on the computer using the file and a stored image that represents the first software stack; and

executing the task sequence by the computer to use the file and the stored image to install the second software stack.

2. The method of claim 1, further comprising receiving, by the computer, metadata identifying a correlation between a software component represented by the first software stack and a software component represented by the second software stack.

3. The method of claim 1, wherein the file and the stored image are stored in a logically-protected region of a computer-readable medium of the computer.

4. The method of claim 3, wherein executing comprises executing the task sequence to install the second software stack on the same computer-readable medium.

5. The method of claim 3, wherein:

the task sequence further includes instructions for;

rebooting the computer into a memory-resident operating system; and

after rebooting, erasing a portion of the computer-readable medium that does not store the file and the stored image, and

the method further comprises performing the rebooting and erasing as instructed by the task sequence.

6. The method of claim 5, wherein erasing the portion of the computer-readable medium comprises erasing the first software stack from the computer-readable medium.

7. The method of claim 5, wherein executing comprises executing the task sequence to install the second software stack in the erased portion of the computer-readable medium.

8. The method of claim 1, further comprising receiving a second file representing a difference between the first software stack and a third software stack, wherein the task sequence further includes instructions for installing the second software stack based on the first file, the second file, and the stored image.

9. A computer-readable medium storing computer-executable instructions for a computer to perform a method, the method comprising installing a second software stack based on a file and a stored image, wherein the file represents a difference between a first software stack and the second software stack, and wherein the stored image represents the first software stack.

10. The computer-readable medium of claim 9, wherein the file and the stored image are stored in a logically-protected region of a computer-readable medium of the computer.

11. The computer-readable medium of claim 10, wherein installing comprises installing the second software stack on the same computer-readable medium.

12. The computer-readable medium of claim 10, wherein the method further comprises:

rebooting the computer into a memory-resident operating system; and

after rebooting, erasing a portion of the computer-readable medium that does not store the file and the stored image.

13. The computer-readable medium of claim 12, wherein erasing the portion of the computer-readable medium comprises erasing the first software stack from the computer-readable medium.

14. The computer-readable medium of claim 12, wherein installing comprises installing the second software stack in the erased portion of the computer-readable medium.

15. The computer-readable medium of claim 9, wherein installing further comprises installing the second software stack based on the file, the stored image, and a second file that represents a difference between the first software stack and a third software stack.

16. An apparatus, comprising:

a computer-readable medium storing computer-executable instructions for a computer to perform a method, the method comprising installing a second software stack based on a file and a stored image, wherein the file represents a difference between a first software stack and the second software stack, and wherein the stored image represents the first software stack; and

a processor configured to execute the computer-executable instructions.

17. The apparatus of claim 16, wherein the file and the stored image are stored in a logically-protected region of a computer-readable medium of the computer.

18. The apparatus of claim 17, wherein installing comprises installing the second software stack on the same computer-readable medium.

19. The apparatus of claim 17, wherein the method further comprises:

rebooting the computer into a memory-resident operating system; and

after rebooting, erasing a portion of the computer-readable medium that does not store the file and the stored image.

20. The apparatus of claim 19, wherein erasing the portion of the computer-readable medium comprises erasing the first software stack from the computer-readable medium.
