Math expression in attributes/default.rb

Chef Infra (archive)

Does chef supports math expressions in attributes/default.rb ?
I need to set up set_unless[:apache][:prefork][:startservers] depending
on the total memory and some factors…

Does anybody known formula for other apache settings
like this:

set_unless[:apache][:prefork][:startservers]
set_unless[:apache][:prefork][:minspareservers]
set_unless[:apache][:prefork][:maxspareservers]
set_unless[:apache][:prefork][:serverlimit]
set_unless[:apache][:prefork][:maxclients]
set_unless[:apache][:prefork][:maxrequestsperchild]

?

Thanks.

It's ruby.

So you can put arbitrary expressions as the code to set attributes, scope
and timing notwithstanding.
