Share an Augeas handler for all resources of a provider
Fix provider specs
kernel_parameter: fix grub2 provider for shared handler
sysctl: fix provider for shared handler
sysctl and pg_hba: make tmpdir outside of contexts
shellvar: Fix @logs test in specs (value= succeeds, flush fails)
sshd_config: reuse aug handler in match_exists?
Doc for flush
Mark aug_handler as @api private
Do not reload tree by default in augsave!
Call super in providers that redefine flush
Use a new Augeas handler for @aug_version to avoid messing up with the shared handler when resource is not defined
Add a new supported? method to replace using_post_resource_eval? and regexpi_supported?
Improve doc on closing handlers for augopen
