Fix issue with EBS device mount failure on boot due to unavailability

[bscriver123]

Description

This pull request addresses the issue where the OS fails to mount an EBS device that is not available at the time of boot. The current fstab entry is causing the mount to fail due to the delay in attaching the EBS device, especially when it takes longer to attach during boot time.

Proposed Changes

• Modify the fstab entry to handle the delay in attaching the EBS device during boot time.
• Implement a mechanism to wait for the EBS device to become available before attempting to mount it.
• Add error handling to gracefully handle the case where the EBS device is not available immediately at boot.

Testing

• Tested the changes on various systems to ensure the EBS device is successfully mounted even when it takes longer to attach.
• Verified that the error handling mechanism works as expected when the EBS device is not available at boot time.
