Zcc_apt_pipeliningzApt PipeliningzConfigure apt pipelininga This module configures apt's ``Acquite::http::Pipeline-Depth`` option,
which controls how apt handles HTTP pipelining. It may be useful for
pipelining to be disabled, because some web servers, such as S3 do not
pipeline properly (LP: #948461).
Value configuration options for this module are:
* ``os``: (Default) use distro default
* ``false`` disable pipelining altogether
* ````: Manually specify pipeline depth. This is not recommended.zapt_pipelining: falsezapt_pipelining: oszapt_pipelining: 3Úapt_pipelining)ÚidÚnameÚtitleÚ descriptionÚdistrosÚ frequencyZexamplesZactivate_by_schema_keys)r ÚcfgÚcloudÚargsÚreturnc C st |j ddƒ}t|ƒjƒ jƒ }|dkr2tdttƒ n>|d kr>d S |dd„ td d
