4Subject: [PATCH] sd-boot: stub: check LoadOptions contains data
5
6With some UEFI shells LoadOptionsSize is reported being > 0
7but the corresponding LoadOptions does not contain any data
8(the first element has value 0).
9
10When that happens, the stub feature that allows .cmdline to be
11replaced by what's in LoadOptions ends up copying nothing/random
12data to the kernel cmdline resulting in different kinds of boot
13problems.
14
15To fix this, add a check to see if LoadOptions contains data
16before replacing the .cmdline.
17
18Upstream-Status: Accepted [https://github.com/systemd/systemd/pull/5467]
19
20Fixes [YOCTO #11078].
