What is the minimum USB key size required for creating a Support Live image?

The minimum USB key size required for creating a Support Live image is 4GB. This size is necessary to ensure that there is enough storage capacity to accommodate the complete image along with any additional files, diagnostic tools, or system recovery options that might be included.

Support Live images are designed to offer a comprehensive troubleshooting and recovery solution, which necessitates having sufficient space for all the tools and resources that may be required during support sessions. A 4GB USB key strikes a balance between being large enough to hold these files while also being widely available and easily usable in various hardware configurations.

Selecting a smaller size would likely result in insufficient space for the image and its required components, whereas opting for a larger size is not necessary for this specific purpose. Thus, using a 4GB USB key meets the minimum requirement efficiently.
