There's a way to specify add_options instead of options parameter in the menuentry stanza. I have two questions about the two parameters since there's no real answer in the rEFInd manual that would clarify this. Can add_options and options be mixed? Will the two following be concatenated into a longer one? options "..." add_options "..." Can I use multiple add_options? For instance: add_options "..." add_options "..." add_options "..." I'm asking because this would ease kernel options management...

This actually affects different Debian ISOs, so it doesn't even have to be different distributions. So far I tested multiple Ubuntu/Debian/Linux Mint images, and only Debian has issues -- the others boot well when many images of the same kind (different versions) are copied to the pendrive. I asked about this on a Debian Live mailing list, and they don't really know what's going on. I also checked what efishell says, and I viewed the .disk/info file after switching to each of the Debian ISOs, and...

This is a continuation of some other topic[1], but I wanted to make it a separate issue since it's really an interesting one. First of wall, I have the following partitions on my multiboot pendrive (which actually is an SD card plugged into an external SD card reader): # lsblk /dev/sdb NAME SIZE FSTYPE TYPE LABEL MOUNTPOINT UUID sdb 28.9G disk ├─sdb1 100M vfat part SD_ESP AD3E-8645 ├─sdb2 3G iso9660 part Ubuntu 18.04.4 LTS amd64 2020-02-03-18-40-13-00 ├─sdb3 3G iso9660 part Ubuntu 19.10 amd64 2019-10-17-12-53-34-00...

As for the signing EFI tools -- I've read about some security concerns where people don't want to sign tools like KeyTool or MokManager, because someone can use them without any control when they get access to the machine. Those people suggested to set the supervisor password for EFI, then when you want to use the tools, you simply go to the EFI settings, enter the pass, turn the Secure Boot mode off, and then boot and load the binaries. When you finish, you just enable Secure Boot again. Is this...

I'll try to ask on some Debian ML, because it's weird that Ubuntu works just fine and Debian has issues...

Refreshing the boot entries doesn't seem to work, so I think the machine doesn't support sd cards as boot device at all. I'll try to look for the driver though, and maybe I'll find something useful.

I have an SD card reader built in my laptop, and I wanted to boot a regular ubuntu live image from it, but it looks like rEFInd can't detect the device. The SD card works well (also is the built in SD card reader), and when I plug it in a USB card reader, then I'm able to boot from it. Should something be additionally configured to make it work?
