Cannabis landraces. The essential characteristic of landraces is that they’re domesticates. As Dr. Ernest Small writes in Cannabis: A Complete Guide, “The term landrace (land race) refers to populations of domesticated plants that were selected over many generations by farmers in a region.” Selected traits can include high-quality fibre, large nutritious seeds, or highly aromatic inflorescences that are rich in THC.

The widespread claim on the Internet that landraces are wild plants created solely by nature is misleading. No doubt these traditional domesticates are typically region-specific and adapted to their local environment through natural selection. But their defining qualities are the result of humans consciously and unconsciously selecting for desired products, in some regions over many millennia.

Traditional Asian ‘drug-type’ strains can be grouped into two main types: domesticates for resin (charas), which are found in the Himalaya, Hindu Kush, Central Asia, and Middle East; and domesticates for bud (ganja), which originate in subtropical and tropical India and Southeast Asia.

Crucially, these ancient plants are an invaluable reservoir of biodiversity. See the essential new study from McPartland & Small, ‘A classification of endangered high-THC cannabis (Cannabis sativa subsp. indica) domesticates and their wild relatives’.

Ubuntu's Apache2 default configuration is different from the upstream default configuration, and split into several files optimized for interaction with Ubuntu tools. The configuration system is fully documented in /usr/share/doc/apache2/README.Debian.gz. Refer to this for the full documentation. Documentation for the web server itself can be found by accessing the manual if the apache2-doc package was installed on this server.

The configuration layout for an Apache2 web server installation on Ubuntu systems is as follows:

/etc/apache2/
|-- apache2.conf
|       `--  ports.conf
|-- mods-enabled
|       |-- *.load
|       `-- *.conf
|-- conf-enabled
|       `-- *.conf
|-- sites-enabled
|       `-- *.conf
          

• apache2.conf is the main configuration file. It puts the pieces together by including all remaining configuration files when starting up the web server.
• ports.conf is always included from the main configuration file. It is used to determine the listening ports for incoming connections, and this file can be customized anytime.
• Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/ directories contain particular configuration snippets which manage modules, global configuration fragments, or virtual host configurations, respectively.
• They are activated by symlinking available configuration files from their respective *-available/ counterparts. These should be managed by using our helpers a2enmod, a2dismod, a2ensite, a2dissite, and a2enconf, a2disconf . See their respective man pages for detailed information.
• The binary is called apache2. Due to the use of environment variables, in the default configuration, apache2 needs to be started/stopped with /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not work with the default configuration.

By default, Ubuntu does not allow access through the web browser to any file apart of those located in /var/www, public_html directories (when enabled) and /usr/share (for web applications). If your site is using a web document root located elsewhere (such as in /srv) you may need to whitelist your document root directory in /etc/apache2/apache2.conf.

The default Ubuntu document root is /var/www/html. You can make your own virtual hosts under /var/www. This is different to previous releases which provides better security out of the box.

Please use the ubuntu-bug tool to report bugs in the Apache2 package with Ubuntu. However, check existing bug reports before reporting a new bug.

Please report bugs specific to modules (such as PHP and others) to respective packages, not to the web server itself.
