Mount Configuration

Additional filesystems can be declared as "mounts", specified in the mounts object. Keys in this object are names of mount points from portable config. Values are objects with configuration of mount points. The parameters are similar to the ones in the Linux mount system call. Only mounts from the portable config will be mounted.

type (string, required) Linux, filesystemtype argument supported by the kernel are listed in /proc/filesystems (e.g., "minix", "ext2", "ext3", "jfs", "xfs", "reiserfs", "msdos", "proc", "nfs", "iso9660"). Windows: ntfs
source (string, required) a device name, but can also be a directory name or a dummy. Windows, the volume name that is the target of the mount point. \?\Volume{GUID}\ (on Windows source is called target)
options (list of strings, optional) in the fstab format https://wiki.archlinux.org/index.php/Fstab.

Example (Linux)

"mounts": {
    "proc": {
        "type": "proc",
        "source": "proc",
        "options": []
    },
    "dev": {
        "type": "tmpfs",
        "source": "tmpfs",
        "options": ["nosuid","strictatime","mode=755","size=65536k"]
    },
    "devpts": {
        "type": "devpts",
        "source": "devpts",
        "options": ["nosuid","noexec","newinstance","ptmxmode=0666","mode=0620","gid=5"]
    },
    "data": {
        "type": "bind",
        "source": "/volumes/testing",
        "options": ["rbind","rw"]
    }
}

Example (Windows)

"mounts": {
    "myfancymountpoint": {
        "type": "ntfs",
        "source": "\\\\?\\Volume\\{2eca078d-5cbc-43d3-aff8-7e8511f60d0e}\\",
        "options": []
    }
}
