Matching Expressions

Hotfixes can provide a for key with an array of supported systems. The expressions are evaluated using Symfony's ExpressionLanguage and as such can handle some pretty complex stuff.

For a hotfix to be considered supported, at least one of the expressions must evaluate to true.

Example:

for:
    - lsb.id=='raspbian'
    - lsb.id=='ubuntu' and lsb.release=>'16.04'

System facts

Distribution

Information is retrieved using lsb_release or the /etc/os-release file.

  lsb.id            Distribution ID (ex. ubuntu or raspbian)
  lsb.description   Pretty description
  lsb.release       Version number (ex. 16.04 or 8)
  lsb.codename      Release codename (ex. xenial, not always present)
