RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Hello,
for Satellite 6 bootdisk support, we would like be able to generate bootdisks with ixpe.efi chainbooted from Grub2. This allows specifying script location via arguments. For BIOS we use:
default ipxe
label ipxe
kernel /ipxe
initrd /script
For EFI we would like to do the same, but this does not work:
set default=0
set timeout=1
menuentry "Chainload iPXE - this does not work" {
linuxefi /ipxe.efi
initrdefi /script.ipxe
}
menuentry "Chainload iPXE - this does not work either" {
search --no-floppy --set=root -f /ipxe.efi
chainloader /ipxe.efi chain /script.ipxe
}
Arguments are ignored by the EFI firmware at the moment.
Can you guys estimate how feasible is implementing such a feature, thanks. If that turns out to be hard, we could compile our own ipxe.efi with embedded script that chainloads another one from the media.

Proof-of-concept patch
Lukas, can you please try the attached prototype patch? I can pass EFI command line arguments from iPXE to iPXE, e.g.
iPXE> chain ipxe.efi echo Hello world!
but I haven't tried it with grub.
Unfortunately, I am not able to boot that from Grub2, it looks like there is no way of providing entry options. I am afraid the only solution is to build a regular UEFI boot image (FAT image with iPXE EFI ROM) with embedded "chain script.ipxe" command. The thing I was trying to avoid (to carry own build of ipxe with embedded script in Satellite repositories).
