func IsPathInPrefixList ¶

func IsPathInPrefixList(path string, prefix []string) bool

IsPathInPrefixList is a small function for CRIU restore to make sure mountpoints, which are on a tmpfs, are not created in the roofs.

func MountRootDirForRestore ¶

func MountRootDirForRestore(next types.Restore) types.Restore

CRIU has a few requirements for a root directory: * it must be a mount point * its parent must not be overmounted c.config.Rootfs is bind-mounted to a temporary directory to satisfy these requirements.

func SetupMountsForRestore ¶

func SetupMountsForRestore(next types.Restore) types.Restore

Tries to set up the rootfs of the container to be restored in the same way runc does it for initial container creation. Even for a read-only rootfs container runc modifies the rootfs to add mountpoints which do not exist. This function also creates missing mountpoints as long as they are not on top of a tmpfs, as CRIU will restore tmpfs content anyway.
