pureInfoProperty :: Desc -> Info -> Property

askInfo :: (Info -> Val a) -> Propellor (Maybe a)

os :: System -> Property

getOS :: Propellor (Maybe System)

ipv4 :: String -> Property

Indidate that a host has an A record in the DNS.

TODO check at run time if the host really has this address. (Can't change the host's address, but as a sanity check.)

ipv6 :: String -> Property

Indidate that a host has an AAAA record in the DNS.

alias :: Domain -> Property

Indicates another name for the host in the DNS.

When the host's ipv4/ipv6 addresses are known, the alias is set up to use their address, rather than using a CNAME. This avoids various problems with CNAMEs, and also means that when multiple hosts have the same alias, a DNS round-robin is automatically set up.
