As recently as last month, someone's patch to add such support was rejected for this reason [1]. --Sean [1] https://lore.kernel.org/linux-arm-kernel/20220812084613.GA3107@willie-the-truck/

It's quite frustrating, really. It must not be that important. From the last time, IMO Christophe's version was much closer to being merged than this series.

It's quite frustrating, really. I'm not sure I'm following your comments. What's frustrating exactly ? Daniel

However, I figured maintainers don't want the changes. This is a common occurrence in industry, people may submit once or twice, no traction and they give up. I suppose it's a combination of problems. Christophe's don't have the same features, so they are really totally different but conflicting. Daniel
v4 release changes * Updated insert-sys-cert tool to change command line symbols after compilation. This tool is used to release binary kernels internally to companies and then later insert certificates for each product by consumers of the binary kernel. Cisco uses this tool for this purpose. Cisco has a similar need for the command line to be modified on a binary released kernels similar to how certificates are setup. * Added global symbols to hold append and prepend values. These changes follow the system certificate code to allow the insert-sys-cert tool to be used. * Added a test case to confirm functionality. Seemed sensible to add this to make sure everything is working. * Dropped powerpc changes Christophe Leroy has reservations about the features for powerpc. I don't think his reservations are founded, and these changes should fully work on powerpc. However, I dropped these changes so Christophe can have more time to get comfortable with the changes.
