Types ¶

type PartitionInfo ¶

type PartitionInfo struct {
	// The active + inactive kernel device partitions (e.g. /dev/nvme0n1p2).
	ActiveKernel      string
	ActiveKernelNum   string
	InactiveKernel    string
	InactiveKernelNum string
	// The active + inactive root device partitions (e.g. /dev/nvme0n1p3).
	ActiveRoot   string
	InactiveRoot string
	// The A + B miniOS device partitions.
	MiniOSA string
	MiniOSB string
}

partitionsInfo holds active/inactive root + kernel partition information.

func GetPartitionInfo ¶

func GetPartitionInfo(root string, rootDisk string, rootPartNum string) PartitionInfo

GetPartitionInfo retrieves relevant kernel and root info for a specific root
