There's also the 'operatingsystemrelease' fact that will evaluate to the
full version. You could do this:
Facter.add('operatingsystemmajor') do
setcode do
Facter.value('operatingsystemrelease').split('.').first
end
end
If you do choose to use the shell command, you can do this:
Facter.add('operatingsystemmajor') do
setcode("cat /etc/redhat-release | awk \{'print $3'\}|cut - c1")
end
Passing a string to the setcode method in Facter will automatically pipe
the command to Facter::Util::Resolution.exec which will execute the command
and return the value from stdout. Using Facter::Util::Resolution.exec() is
better than %x{} because it has a built-in timeout (so if your command
hangs your facter/puppet run won't). It also handles nil values well, has
a built-in PATH environment variable, and handles invalid commands a bit
better than %x{} (plus, just passing an argument to setcode is a bit
cleaner).
