This is the development version of Kanrisuru. Since this is still a pre-1.0 release, we don't recommend using this in system-critical production environments.

FS Mount Options

The Kanrisuru::Util::FsMountOpts class is a lookup utility module that helps with validating if a device type is valid, as well as the various options for that device type. These options are primarly used with filesystem mounts with the mount command, as well as Kanrisuru::Remote::Fstab class.

Public Class Methods

get_device

Returns the full set of device options for a device.

Kanrisuru::Util::FsMountOpts.get_device('ext4')
{
  "acl": "boolean",
  "noacl": "boolean",
  "bsddf": "boolean",
  ... 
  "dioread_lock": "boolean",
  "dioread_nolock": "boolean",
  "i_version": "boolean"
}

get_device_opt

Checks for a given device, the option mapped to that device.

Kanrisuru::Util::FsMountOpts.get_device_opt('common', 'owner')
'boolean'

[]

Returns the full set of device options for a device.

Kanrisuru::Util::FsMountOpts['ext4']
{
  "acl": "boolean",
  "noacl": "boolean",
  "bsddf": "boolean",
  ... 
  "dioread_lock": "boolean",
  "dioread_nolock": "boolean",
  "i_version": "boolean"
}

Lookup Table

Table is structured as a hash of device type names, mapped to their options. Each option key is the name of the option used in linux, and maps to the argument type expected when constructing a command. boolean would be a flag, whereas value would be an option argument.
