[libvirt] [RFC] net-dhcp-leases: Query: Reg: Leases API Script

Q1. The --dhcp-script option will require libvirt to provide a script or executable file to be run. Now as the man page says, this file is executed "Whenever a new DHCP ease is created, or an old one destroyed". Life was easy with the script, as it used the command sed to remove the destroyed lease. eblake had suggested me to use a C program instead. So I wanted to finalize whether to go with C or continue with shell script. Q2. The above executable file will be writing the custom formatted lease parameters to a file "dnsmasq-ip-mac.status" (suggestion open for name). This newly created/updated file will be parsed by the API. We need to decide the format for the file. Do we continue with space separated parameters as before? Q3. What should be the location of the above two files? Is there any example that I can follow in libvirt for deploying custom-script files/C programs which are not to be linked? Script is attached. -- Nehal J Wani
