set net0.dhcp/hostname not working as expected

[bothwell]

Thanks for this. I would like to ask how something similar can be done when ipxe booting a windows OS ?

can you perhaps guide me in the correct direction. basically would like
to dynamically assign computer name at boot.


[You are not doing anything that will pass iPXE's concept of the hostname through to your Linux OS.

You are currently going via pxelinux, so you would need to find a way to get pxelinux to pass a hostname through to your OS. If you avoid using pxelinux and instead use iPXE to load your kernel+initrd directly, then you can pass iPXE's hostname as a kernel command-line parameter. For example:

Code:

kernel vmlinuz hostname=${hostname}
initrd initrd.img
boot

If you then examine /proc/cmdline from within the running OS, you will see "hostname=abc.123" as expected.

Unfortunately, each Linux distro handles networking command-line parameters in a different way. You will need to find out what syntax your distro requires in order to set the hostname via a kernel command-line parameter.
