The mount package contains utilities for mounting Linux devices of the following types: tmpfs, hugetlbfs, btrfs and ext4.

It allows for the mounting of in-memory file systems of specific sizes and specified page sizes.

func IsMemoryFs

func IsMemoryFs(path string) bool

Returns whether the path is an in memory file system file system (either hugetlbfs or tmpfs)

func IsTmpfs

func IsTmpfs(path string) bool

Returns whether the path is a tmpfs file system

func MountExt4

func MountExt4(device, path string, readonly, sync bool) error

MountExt4 mounts the specifed ext4 volume device at the specified path The readonly flag allows the device to be mounted as read only The sync flag can be used to enforce synchronous device access

func MountTmpfs

func MountTmpfs(path string, size int64) error

MountTmpfs mounts a tmpfs file system of the specified size at the provided path

func RemountReadOnly

func RemountReadOnly(source, target string) error

RemountReadOnly remounts the specified source device at the target path as read only
