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.
