We have a bare machine with PXE and a server with a Linux disk image. Need the flow to get this image onto the bare machine's disk. I don't know of anything already available with such functionality but it would be cool to build one: 1. On PXE server side, setup a webserver with images 2. Compile a kernel (with all drivers for your target hardware) + an initrd with /sbin/init which sets up network, fdisk/mkfs's the filesystem, wget -O - http:///image.tar.xz|xzcat |tar xv everything as per kernel parameters. Or if you're using 'disk images', then wget -O - |xzcat|dd if=/dev/stdin of=/dev/$device. You also need to resize partitions to the target sizes after copying the image. which is why I mentioned 'mkfs+tar' otherwise with dd you need to resize2fs (or equivalent filesystem resize tool). 3. Create per client pxelinux.cfg configuration (in case client's settings differ from defaults), with something like: linux /vmlinuz append initrd=/initrd.gz network=eth0;static;172.16.0.3/27 img=gentoo-x64 drive=sda It would be really cool to build something like that yourself :). Thanks to both you and Saurabh for the suggestions. And now I'm invoking the ILUGD torture clause: if you suggest something in public, you are automagically volunteered to do it! So when can we expect a first-cut implementation for testing, Ashish? :) It'll happen, it'll happen in our lifetimes. :) In the meantime I found these, which may be useful starting points. SystemImager in particular seems well-suited: http://svn.oscar.openclustergroup.org/trac/oscar http://wiul.org/ http://kaboot.ainkaboot.co.uk/ http://wiki.systemimager.org/ SystemImager looks closer to what you're looking and has more functionality. - -- Ashish SHUKLA “It is rare that one can see in a little boy the promise of a man, but one can almost always see in a little girl the threat of a woman.” (Alexandre Dumas) Sent from my Emacs -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.18 (FreeBSD) iQIcBAEBCgAGBQJQDOsSAAoJEMdGz6nnT6SwLCUP/j8Bvcaev/WYUEfBlrW0QM+X i4sfmYBErTsXlhju84/dkJfK4mRHw0jj+hnXJ/faAeNsOONt8+8iTOmh8E9W46xD mBRA8naiMWRSrCyCNkrLiX4YaJrb6weh5SWTejKepI80YHEv28qxq8abu2aNhdZn mtxNc++U6W+9RGVwSkPHI3/ttroB9hwnd7CS0qznAN5lF7IM74A9yC0/InkWNlKs DDEAuRXTgb4SqqDNc/EOEwnlJ4pK/u6aMhxMKqqMZNKNOEoPoE/ooe7w/5Gc21rB ZyoGECjT05pZBLHhNHVZSNGxrMh1cikUWUlF7E5dWV/5GSHr0kPPUa5jucyunkZ6 b+QKQN6MjHI4sl0Fh+jH1JXH79T95XPesRqf8UP2FChgxSRYJ8mK01Y6dt8Jts0D KnOSpu6Ukl7VMNBtzep3CHb7zSAx5/o6eA9u0I27iHTtvNktJrrwQWVldnLyypkt Fp/Fh532fLF0dvV5LEofHy6Ecy2f+6S3MAVWm1OX1fqlbCwNxEr9YE1Qgi48x5+m 6ljY5t/aK8MJ7RLlzFndXsziBRmO48RVUQSddg/EHotbjUDPcNhvo/sb2vqKnePI YO1IZM0c0xd8JvV0ug2USiG5UrHsNSW0So8f5zNVO2qfiI6AMcqsSmTgXg67k4Db nS/unZYIKshpvjLvr3Pw =TBs6 -END PGP SIGNATURE- ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd

However, one small issue: Baud=115200 That will just kill whatever speed you could get from the modem. I typically set baud to 3686400 or higher. Even the old Reliance ZTE dongle I'm using handles that.
