Good Afternoon,
As per the installation guide, section 30.2.2 I’ve created an efidefault file at /var/lib/tftpboot/pxelinux/pxelinux.cfg/efidefault
However, this file is never requested by the 64 bit PXE loader (bootx64.efi), as shown by tcpdump:
75 RRQ "/pxelinux/42272635-0011-5053-ACF2-82A100E615F2" octet tsize 0 blksize 512 59 RRQ "/pxelinux/01-00-50-56-A7-BA-BF" octet tsize 0 blksize 512 47 RRQ "/pxelinux/C13F3F6E" octet tsize 0 blksize 512 46 RRQ "/pxelinux/C13F3F6" octet tsize 0 blksize 512 45 RRQ "/pxelinux/C13F3F" octet tsize 0 blksize 512 44 RRQ "/pxelinux/C13F3" octet tsize 0 blksize 512 43 RRQ "/pxelinux/C13F" octet tsize 0 blksize 512 42 RRQ "/pxelinux/C13" octet tsize 0 blksize 512 41 RRQ "/pxelinux/C1" octet tsize 0 blksize 512 40 RRQ "/pxelinux/C" octet tsize 0 blksize 512 49 RRQ "/pxelinux/efidefault" octet tsize 0 blksize 512
I’ve worked around this by placing a separate efidefault in the root of the pxelinux directory - however this is undesirable as this means I have to maintain separate configs for BIOS and UEFI.
Does anyone know why this is not behaving as documented? Regards,

No, but I'll confirm your observation that the efidefault file won't be found unless it's located in the top-level tftp directory.
IIRC the line 49 RRQ "/pxelinux/efidefault" octet tsize 0 blksize 512 In the output below means look in /var/lib/tftpboot//pxelinux/efidefault Not /var/lib/tftpboot//pxelinux/pxelinux.cfg/efidefault i.e. it is rooted at the root of your tftpboot structure.
Even when this disclaimer is not here: I am not a contracting officer. I do not have authority to make or modify the terms of any contract.
