# etc_fstab
|
|
|
|
Use the `etc_fstab` InSpec audit resource to test information about all partitions and storage devices on a Linux system.
|
|
|
|
<br>
|
|
|
|
## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v1.37.6 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
An etc_fstab rule specifies a device name, its mount point, its mount type, the options its mounted with,
|
|
its dump options, and the order the files system should be checked.
|
|
|
|
Use the where clause to match a property to one or more rules in the fstab file:
|
|
|
|
describe etc_fstab.where { device_name == 'value' } do
|
|
its('mount_point') { should cmp 'hostname' }
|
|
its('file_system_type') { should cmp 'list' }
|
|
its('mount_options') { should cmp 'list' }
|
|
its('dump_options') { should cmp 'list' }
|
|
its('file_system_options') { should cmp 'list' }
|
|
end
|
|
|
|
Use the optional constructor parameter to give an alternative path to fstab file:
|
|
|
|
describe etc_fstab(hosts_path).where { device_name == 'value' } do
|
|
its('mount_point') { should cmp 'hostname' }
|
|
its('file_system_type') { should cmp 'list' }
|
|
its('mount_options') { should cmp 'list' }
|
|
its('dump_options') { should cmp 'list' }
|
|
its('file_system_options') { should cmp 'list ' }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Properties
