VM space

For the services we are planning on VM'ing. The current free space on the VMhosts are:

Forum
girassol - 130GB
gaivota - 1000GB
azul - 16GB + 950GB
KB
amarela - 480GB
vermelha - 650GB

Are MPU happy for me to grab 300GB from gaivota and 200GB vermelha?

Apache 2.4

Though apache 2.4 ships with a compatibility module to allow old style "allow/deny" and the new "require host" directives. The recommendation is that you don't mix and match those directives. Indeed I had problems debugging access problems when trying to use both, so I've been simply disabling the compatibility module !apacheconf.moduleactive_access_compat mSET(no) to force only the new "require" way. Any .htaccess or config that then contains the old access directives throws an apache error.

For the main web servers, homepages, groups, www. The plan will be (ahead of time) to update config something like:

  <IfVersion < 2.4>\n
  order deny,allow\n
  deny from all\n
  </IfVersion>\n
  <IfVersion >= 2.4>\n
  Require all denied\n
  </IfVersion>\n

And provide docs on computing.help for users.
