Package diskfs implements methods for creating and manipulating disks and filesystems methods for creating and manipulating disks and filesystems, whether block devices in /dev or direct disk images. This does **not** mount any disks or filesystems, neither directly locally nor via a VM. Instead, it manipulates the bytes directly. This is not intended as a replacement for operating system filesystem and disk drivers. Instead, it is intended to make it easy to work with partitions, partition tables and filesystems directly without requiring operating system mounts. Some examples: 1. Create a disk image of size 10MB with a FAT32 filesystem spanning the entire disk. Create a disk of size 20MB with an MBR partition table, a single partition beginning at block 2048 (1MB), of size 10MB filled with a FAT32 filesystem. import diskfs "github.com/dave/diskfs" diskSize := 10*1024*1024 // 10 MB diskImg := "/tmp/disk.img" disk := diskfs.Create(diskImg, size, diskfs.Raw) table := &mbr.Table{ LogicalSectorSize: 512, PhysicalSectorSize: 512, Partitions: []*mbr.Partition{ { Bootable: false, Type: Linux, Start: 2048, Size: 20480, }, }, } fs, err := disk.CreateFilesystem(1, diskfs.TypeFat32) Create a disk of size 20MB with a GPT partition table, a single partition beginning at block 2048 (1MB), of size 10MB, and fill with the contents from the 10MB file "/root/contents.dat" import diskfs "github.com/dave/diskfs" diskSize := 10*1024*1024 // 10 MB diskImg := "/tmp/disk.img" disk := diskfs.Create(diskImg, size, diskfs.Raw) table := &gpt.Table{ LogicalSectorSize: 512, PhysicalSectorSize: 512, Partitions: []*gpt.Partition{ { LogicalSectorSize: 512, PhysicalSectorSize: 512, ProtectiveMBR: true, }, }, } f, err := os.Open("/root/contents.dat") written, err := disk.WritePartitionContents(1, f) Create a disk of size 20MB with an MBR partition table, a single partition beginning at block 2048 (1MB), of size 10MB filled with a FAT32 filesystem, and create some directories and files in that filesystem. import diskfs "github.com/dave/diskfs" diskSize := 10*1024*1024 // 10 MB diskImg := "/tmp/disk.img" disk := diskfs.Create(diskImg, size, diskfs.Raw) table := &mbr.Table{ LogicalSectorSize: 512, PhysicalSectorSize: 512, Partitions: []*mbr.Partition{ { Bootable: false, Type: Linux, Start: 2048, Size: 20480, }, }, } fs, err := disk.CreateFilesystem(1, diskfs.TypeFat32) err := fs.Mkdir("/FOO/BAR") rw, err := fs.OpenFile("/FOO/BAR/AFILE.EXE", os.O_CREATE|os.O_RDRWR) b := make([]byte, 1024, 1024) rand.Read(b) err := rw.Write(b)
