Hello Everyone,
I am using foreman in mix with vmware, but experience really serious issue where impossible adjust setting for filename in DHCP, because it super seed from foreman.
We using mass deployment for remote location where use of TFTP or ipxe not an option.
VMware ipxe is not in option because it require change of each vmx file manually to load ipxe into bios.

For file initrd 44M take 1 hour 45 to download through TFTP ?
I have test case build where I am using HTTP/nginx instead TFTP and whole new vm deployment takes about 27 min with VMware.
My request is have ability to set in foreman provisioning settings which type of pxe filename to use. Right now syslinux use lpxelinux.0 which support HTTP and FTP out of the box no need chain files or different scripts to load.
Here my boot menu which I use for HTTP.
