With 7.1, a harddisk install now requires that the iso images be in the partition selected rather than the former approach which had the whole directory tree in "one big lump". This is a good option for some circumstance and should remain. However, since the "one big lump" is still supported (required) for nfs, ftp, or http installs, the code for supporting it is still there. Therefore, this RFE asks for a new harddisk option in addition to the harddisk-iso current option to have a harddisk-directory-tree (one big lump) option. An example of its use is when tailoring comp files or adding addition packages can be debug faster easier if this new option is implemented -- you do not need the disk space for the iso images in addition to the one big lump AND you don't have to spend the time creating the iso images. This is an RFE for 7.2.
Take a look at bug #18019 (and the countless dupes) and you'll see why we took it away. For some reason, a *lot* of people doing hard drive installs download the tree without setting their ftp client to binary mode. The people doing NFS installs seem to know better. After all the time we've spent dealing with this issue (that really wasn't a bug), we are not going to re-enable this method of installation.
