Hi,
I'm trying to make very big MD_ROOT (300MB) sent using PXEBOOT+TFTPBOOT. No
NFS.
Any reasons for not using NFS ?
I use i386/5.4RC2/TFTPD/PXEBOOT+TFTPBOOT .
(same pb with a 5.3).
Am I missing something obvious?
I'm not sure. tftp itself is able to handle 32MB+ files, but maybe the
loader isn't.
A workaround, no using NFS, could be to tftp a second filesystem image
on boot and mount that from the root filesystem.

I assume that the PXE clients are diskless clients. If so, do they have
enough memory to handle this extremely large image? As for tfpt, it uses
UDP. UDP is usually used for transfer small datagrams, for instance DNS
replies. It is also said to be an unreliable protocol. The client should
repeat the request when no data receives. I doubt this solution is
reliable and flexible enough. My idea for a workaround is creating a
ramdisk from a small boot image, and transfer the less necessary
userland binaries from the boot server to the ramdisk using normal ftp
connection.
