Please add mod_suphp support for virtualmin. I think it's very simple as the suphp module is provided by most linux dists, Very similar configuration to Suexec, Easily configurable, ...
I prefer mod_suphp for its security :
It's default execution mod prefered by cpanel, directadmin, ...
It checks each script for permission, owner and some other stuffs before running the script
Low memory consumption
Server managers are used to mod_suphp as its the default execution type on most control panels. I myself just prefer the mod_suphp as the first choice in a shared hosting server.
CGI Can be completely disabled on virtual servers without missing the owner execution of php scripts using mod_suphp . ( some servers just host php sites and doesn't need the cgi module at all ) Thanks
