[chef] Re: Re: Inserting multiple lines through Chef::Util::FileEdit

[Juanje Ojeda Croissier < >]

Chef::Util::FileEdit is a bit tricky and it must be the last option to
be used. I do use it myself sometimes, but I try to replace it with
templates or proper idempotence resources as soon as I can.

And for your case (/etc/fstab), there is already a resource to manage
the mount points that you may want to use:
http://docs.opscode.com/resource_mount.html

I hope this helps you.
