Deployment and updating of applications and drivers on a client device using an extensible markup language (XML) configuration file
View Patent ↗The deployment and updating of applications and drivers on a client device having a write-filter is described. A first deployment extensible markup language (XML) configuration file is obtained for deploying a first application or driver at the client device. A first application or driver is deployed on the client device based on the first deployment XML configuration file, while the write-filter of the client device is disabled. The write-filter is enablable to prohibit a file stored on the client device with the write-filter enabled from persisting across a reboot of the device. Following the deployment, automatic updating is performed by determining whether an autoupdate is available, obtaining a second deployment XML configuration file for updating the first application or driver, and updating the first application or driver based on the second deployment XML configuration file, while the write-filter is disabled. The automatic updating may be repeated.
1. A method for deploying and updating a client device, the method comprising:
obtaining, from a configuration repository, a first deployment configuration file for deploying a first software component at the client device;
disabling a write-filter on the client device, wherein the write-filter is enablable to prohibit a file stored on the client device with the write-filter enabled from persisting across a reboot of the client device;
deploying, on the client device while the write-filter is disabled, the first software component based on the first deployment configuration file;
after deploying the first software component, updating on the client device, including:
determining whether an autoupdate is available;
obtaining, from the configuration repository, a second deployment configuration file for updating the first software component at the client device; and
updating, on the client device while the write-filter is disabled, the first software component based on the second deployment configuration file.
2. The method of claim 1 , wherein the first software component is selected from: an application and a device driver.
3. The method of claim 1 , wherein the determining whether the autoupdate is available comprises:
determining whether the configuration repository stores a deployment configuration file for updating the first software component.
4. The method of claim 1 , further comprising:
storing the first deployment configuration file in a location of a memory of the client device that is exempt from the write-filter.
5. The method of claim 1 , further comprising:
deleting from a memory of the client device the second deployment configuration file.
6. The method of claim 1 , wherein the first deployment configuration file and the second deployment configuration file are extensible markup language (XML) files.
7. An article of manufacture comprising a non-transitory computer-readable medium storing instructions for deploying and updating software components on a client device having a write-filter, the instructions, when executed by a processor, for causing the processor to:
obtain, from a configuration repository, a first deployment configuration file for deploying a first software component at the client device;
disable a write-filter on the client device, wherein the write-filter is enablable to prohibit a file stored on the client device with the write-filter enabled from persisting across a reboot of the client device;
deploy, on the client device while the write-filter is disabled, the first software component based on the first deployment configuration file;
after the first software component is deployed, update the client device, including instructions to:
determine whether an update is available at the configuration repository;
obtain, from the configuration repository, a second deployment configuration file for updating the first software component at the client device; and
update, on the client device while the write-filter is disabled, the first software component based on the second deployment configuration file.
8. The article of manufacture of claim 7 , wherein the first software component is selected from: an application and a device driver.
9. The article of manufacture of claim 7 , wherein the instructions to determine whether the update is available comprise instructions to:
determine whether the configuration repository stores a deployment configuration file for updating the first software component.
10. The article of manufacture of claim 7 , further comprising instructions to:
store the first deployment configuration file in a location of a memory of the client device that is exempt from the write-filter.
11. The article of manufacture of claim 7 , further comprising instructions to:
delete from a memory of the client device the second deployment configuration file.
12. The article of manufacture of claim 7 , wherein the first deployment configuration file and the second deployment configuration file are extensible markup language (XML) files.
13. A client device comprising:
a processor having access to a memory, wherein the memory stores instructions executable by the processor, the instructions, when executed by the processor, cause the processor to:
obtain, from a configuration repository, a first deployment configuration file for deploying a first software component at the client device;
disable a write-filter on the client device, wherein the write-filter is enablable to prohibit a file stored on the client device with the write-filter enabled from persisting across a reboot of the client device;
deploy, on the client device while the write-filter is disabled, the first software component based on the first deployment configuration file;
after the first software component is deployed, update the client device, including instructions to:
determine whether an update is available at the configuration repository;
obtain, from the configuration repository, a second deployment configuration file for updating the first software component at the client device; and
update, on the client device while the write-filter is disabled, the first software component based on the second deployment configuration file.
14. The client device of claim 13 , wherein the first software component is selected from: an application and a device driver.
15. The client device of claim 13 , wherein the instructions to determine whether the update is available comprise instructions to:
determine whether the configuration repository stores a deployment configuration file for updating the first software component.
16. The client device of claim 13 , further comprising instructions to:
store the first deployment configuration file in a location of a memory of the client device that is exempt from the write-filter.
17. The client device of claim 13 , further comprising instructions to:
delete from a memory of the client device the second deployment configuration file.
18. The client device of claim 13 , wherein the first deployment configuration file and the second deployment configuration file are extensible markup language (XML) files.
19. The client device of claim 13 , wherein the first software component is executable on an embedded operating system executing on the processor.
20. The client device of claim 13 , further comprising instructions to:
when the first software component is a device driver, verify installation of the first software component.
