func ApplySelinuxLabels ¶

func ApplySelinuxLabels(cfg types.Config, parts types.ElementalPartitions) error

ApplySelinuxLabels sets SELinux extended attributes to the root-tree being installed

func CheckActiveDeployment ¶

func CheckActiveDeployment(cfg types.Config) bool

CheckActiveDeployment returns true if at least one of the mode sentinel files is found

func CopyCloudConfig ¶

func CopyCloudConfig(c types.Config, path string, cloudInit []string) (err error)

CopyCloudConfig will check if there is a cloud init in the config and store it on the target

func CopyFileImg ¶

func CopyFileImg(c types.Config, img *types.Image) error

CopyFileImg copies the files target as the source of this image. It also applies the img label over the copied image.

func CreateFileSystemImage ¶

func CreateFileSystemImage(c types.Config, img *types.Image, rootDir string, preload bool, excludes ...string) error

CreateFileSystemImage creates the image file for the given image. An root tree path can be used to determine the image size and the preload flag can be used to create an image including the root tree data.

func CreateImageFromTree ¶

func CreateImageFromTree(c types.Config, img *types.Image, rootDir string, preload bool, cleaners ...func() error) (err error)

CreateImageFromTree creates the given image including the given root tree. If preload flag is true it attempts to preload the root tree at filesystem format time. This allows creating images with the given root tree without the need of mounting them.

func DeactivateDevices ¶

func DeactivateDevices(c types.Config) error

DeactivateDevice deactivates unmounted the block devices present within the system. Useful to deactivate LVM volumes, if any, related to the target device.

func DeployImage ¶

func DeployImage(c types.Config, img *types.Image) error

DeployImage will deploy the given image into the target. This method creates the filesystem image file and fills it with the correspondant data

func DeployRecoverySystem ¶ added in v2.1.0

func DeployRecoverySystem(cfg types.Config, img *types.Image) error

DeployRecoverySystem deploys the rootfs image from the img parameter and extracts kernel+initrd to the same directory. This can be used for both ISO (all artifacts in same output dir) and raw disks (kernel and initrd in ESP, rootfs squashfs image in recovery partition.

func DumpSource ¶

func DumpSource(c types.Config, target string, imgSrc *types.ImageSource) error

DumpSource sets the image data according to the image source type

func FormatPartition ¶

func FormatPartition(c types.Config, part *types.Partition, opts ...string) error

FormatPartition will format an already existing partition

func GetTempDir ¶

func GetTempDir(c types.Config, suffix string) string

GetTempDir returns the dir for storing related temporal files It will respect TMPDIR and use that if exists, fallback to try the persistent partition if its mounted and finally the default /tmp/ dir suffix is what is appended to the dir name elemental-suffix. If empty it will randomly generate a number

MountRWPartition mounts, or remounts if needed, a partition with RW permissions

func PartitionAndFormatDevice ¶

func PartitionAndFormatDevice(c types.Config, i *types.InstallSpec) error

PartitionAndFormatDevice creates a new empty partition table on target disk and applies the configured disk layout by creating and formatting all required partitions

func SelinuxRelabel ¶

func SelinuxRelabel(c types.Config, rootDir string, raiseError bool) error

SelinuxRelabel will relabel the system if it finds the binary and the context

func SourceFormISO ¶

func SourceFormISO(c types.Config, iso string) (*types.ImageSource, func() error, error)

SourceISO downloads an ISO in a temporary folder, mounts it and returns the image source to be used Returns a source and cleaner method to unmount and remove the temporary folder afterwards.
