[ipxe-devel] Default path in IPXE chain command

[Lee Turchin]

Hi Christian,
Your advice re: IPXE script changes worked and now I am faced with fact that image is too large to be loaded.  But, at least I am making progress toward the bare metal install completion.
Thanks millions sir.
Screenshot attached.

Please note the first line- chain https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2F172.17.11.119%3A8150%2Fsvc%2Fboot&data=01%7C01%7Clee.turchin%40hitachivantara.com%7C416d08bb9ff848cf820808d67b428a27%7C18791e1761594f52a8d4de814ca8284a%7C0&sdata=Zhji8NjciDbl7XpY%2BYjopZ0IUAmH8jtdoHv7WsCWjf8%3D&reserved=0?  Where is the /svc/boot directory location supposed to be on a CentOS 7 system? How do I change that to a viable directory and/or create that same directory with the correct files?

in iPXE there is no default search path, default filename or anything similar.
It is configured via dhcp options, or possibly embeded script.

Your example chain command would load the next iPXE script.
So there is no correct path, or correct files for iPXE But depending on your goal there might be a "required" set of files.

Also a note of your chain command... if you replace net0=${net0/mac:hexhyp} and it's friends with net=${netX/mac:hexhyp} you will get the last opened interface.
for example if dhcp runs before this and net0 and net1 fails but net2 succeds, you would get the data for net2.
Also remember to escape serial and uuid - since they might contain some for url none well handled chars.
