| + | == My understanding of HTTP boot with HTTPFS == | ||
| + | - Download the Linux kernel with fuse support ( or insert fuse module later ) | ||
| + | - download initramfs with | ||
| + | - fuse module | ||
| + | - httpfs executable | ||
| + | - Network setup tools and modules script to set root filesystem to the HTTPFS. | ||
| + | - Boot with this setup. | ||
| + | |||
| + | It seems I am missing many things here, let me try out [[wiki:BootOverNFS|booting over NFS]] first | ||
| + | |||
| + | == Problems with mounting with httpfs == | ||
| + | Check out [[HttpFSProbs]] for details | ||
| + | |||
| + | few worries : | ||
| + | - If FUSE is used to mount root partition, then when actual user logs in, he may not see any of those files as they are mounted by root. | ||
| + | - Need to find FUSE option which will allow everyone to see the file. | ||
| + | - httpfs program does not accept any option :-(, How can I pass options ? | ||
| + | |||
| + | PS: One way out can be that, root mounts iso over HTTP, then uses the local loop to mount that ISO. | ||
| + | I guess that, the ISO mounted by root is mounted using normal mount command, and hence should be readable by all. | ||
| + | and can also support other mount options if needed. \\ | ||
| + | I have not done this experiment yet, need to confirm before proceeding on this path.\\ | ||
| + | Done with this experiment, any user can view files if root remounts the iso file from httpfs with loop. | ||

| + | === June - 2 === | ||
| + | Done nothing useful, just some random reading | ||
| + | |||
| + | === June - 3 === | ||
| + | - Writing PHP code to support booting and using pxelinux from machines with static IP address.\\ | ||
| + | - Stuck with issue of permissions regarding opening files in write mode :-( | ||
| + | |||
| + | === June -4 === | ||
| + | - Suddenly enlightened by the memory that I have code for rom-o-matic :-) | ||
| + | - Got it running on my machine. | ||
| + | - Wrote and sent the patch so that it will be easy to host rom-o-matic on any machine. | ||
| + | - Patched rom-o-matic is hosted at http://www.alien.doesntexist.org/rom-o-matic/ | ||
| + | - Modifying rom-o-matic to support pxeknife [[PxeKnifeRomOMatic]] | ||
| + | |||
| + | === June - 5-6 === | ||
| + | - Done with pxe-generation for both static and dynamic networks | ||
| + | - modified rom-o-matic code to provide user with option to have add inbuilt BKO support. | ||
| + | |||
| + | === June - 9 === | ||
| + | - Getting up rom-o-matic with BKO support on etherboot. done [http://etherboot.org/share/pravin/BKO/rom-o-matic/] | ||
| + | - Because of some wired reason, even original rom-o-matic code is not producing any output. -- solved, the bin/NIC target was not compiled in and error reporting was turned off. | ||
| + | - The latest gpxe code, and gpxe version used by rom-o-matic, both are creating trubble while booting. [[ProbsBKORomOMatic]] | ||
| + | |||
| + | === June - 10 === | ||
| + | - Trying to fix the problem with BKO and Rom-O-Matic integration [[ProbsBKORomOMatic]] | ||
| + | - Adding DSL to pxeknife [[PxeKnifeDSL]] | ||
| + | - Trying to boot it over http. | ||
