This commit does the following: - Splits the podman-systemd.unit.5.md into multiple files - one for each quadlet file type. - Adds the podman-quadlet-basic-usage.7.md for quadlet examples. - Majority of the text in the new files is copied from the podman-systemd.unit.5.md - Adds support for very simple condditional in the markdown_preprocess. - Uses new logic in markdown_preprocess in options/*.md to use a single .md file for both podman subcommands man-pages and quadlet man-pages. This deduplicates the Quadlet man-pages a lot. - Adds new `@@option quadlet:source.md`` preprocess command to import such .md files from options directory.

Set custom DNS servers.
|
|
|
|
This option can be used to override the DNS
|
|
configuration passed to the container. Typically this is necessary when the
|
|
host DNS configuration is invalid for the container (e.g., **127.0.0.1**). When this
|
|
is the case, the << '**DNS=.**' if is_quadlet else '**--dns**' >> flag is necessary for every run.
|
|
|
|
The special value **none** can be specified to disable creation of _/etc/resolv.conf_ in the container by Podman.
|
|
The _/etc/resolv.conf_ file in the image is then used without changes.
|
|
|
|
Note that **ipaddr** may be added directly to the container's _/etc/resolv.conf_.
|
|
This is not guaranteed though. For example, passing a custom network whose *dns_enabled* is set to *true* to **--network** will result in _/etc/resolv.conf_ only referring to the aardvark-dns server. aardvark-dns then forwards to the supplied **ipaddr** for all non-container name queries.
