Its add support for downloading the ISO image via HTTP/FTP with curl or download *.sfs files. The files are downloaded on /run/archiso/curlspace (tmpfs) and setup a loop dev from it (like in archiso_loop_mnt) in the ISO case, or just do a bind mount to /run/archiso/bootmnt in the other case. This hook must be located after archiso_pxe_nbd in mkinitcpio.conf, in that way NBD is the default. New bootparm: * archiso_curl_url=(first form) archiso_curl_url=http://192.168.0.7/archlinux/iso/archlinux.iso (absolute form) Use an absolute URL. Fetch the entire ISO archiso_curl_url=ftp://${pxeserver}/archlinux/iso/archlinux.iso (relative form) Use the as IP the same server where PXE reside. Fetch the entire ISO * archiso_curl_url=(second form) archiso_curl_url=http://192.168.0.7/archlinux/iso/unpacked (absolute form) Use an absolute URL. Where unpacked (an example name) is a directory where ${archisobasedir} ("arch" by default) is located with all *.sfs. This fetch only needed files. archiso_curl_url=ftp://${pxeserver}/archlinux/iso/unpacked (relative form) Use the as IP the same server where PXE reside. Where unpacked (an example name) is a directory where ${archisobasedir} ("arch" by default) is located with all *.sfs. This fetch only needed files. * curlspace_size= Set a size for a tmpfs filesystem where files are downloaded.
