Grab-bag of unsorted topics

• Examine the SyntaxHighlight extension from the point of view of demands on the host (suggested by AndrewT, see also https://phabricator.wikimedia.org/T250763)
• Linux namespaces and cgroups
• Controlling Resources & Privileges with Linux namespaces, cgroups & limits
• conform - nodeinfo
• MediaWiki documentation site management - MySQL DB, /home/mediawiki/images, /home/mwimages/
• Pages yet to be created

• Pages needing work

A bit more specifically, each New World host's filesystem is handled thusly:

Path	Handled by
/etc	Jointly managed by apt which mostly provides default versions of configuration files, and cfengine which installs CSE-specific versions of configuration files
/usr/local/extrafiles /usr/local/extrapackages /usr/local/debpkgs_lists /usr/local/vmimages	cfengine
/proc /sys /dev	The kernel
/tmp /var	Whatever processes are running on the host
/export	The kernel's nfsd (i.e., NFS server)
/import /home	The automounter
Everything else	apt

Configuration management (cfengine)

The cfengine hub.
