OK. I think we want to change this: - as Lennart mentioned in the other reply, we want automount with expiration after a fairly short timeout, and that effectively means no nesting. - nesting also means that (potentially) we have to modify the upper volume to create a directory, at things are ugly if the directory exists but is not empty. Keeping both mount points independent is just nicer. > > (*) This is actually something that'd need to be figure out. > > /boot/efi is the worst choice; either /boot or /efi would be OK, > > but something needs to be chosen. > > /boot/efi is clearly not ideal for a number of reasons, but this is what > we have today and changing this opens up another can of worms.

Packages should not use rpm to put files directly in /boot. Systemd doesn't do this, the kernel doesn't do this (except for %ghost files). grub2 does some directories, but thankfully no files, and shim must stop too. Stuff that rpm manages should be under /usr, and scriptlets should do installation if the config is appropriate. /boot is also subject to external modifications and management, and rpm just isn't the right tool for this. Installing files via rpms also makes it hard to install but not use the package (based on local configuration), or to consume the package for other things (e.g. just booting vms or building images, etc.). > If we are going to change this the only option which makes sense to me > is to go for the systemd default: ESP (if present) mounted at /efi, > XBOOTLDR (if present) mounted at /boot. Yeah. But either choice means that the path harcoding is broken.
