Question
Short question: Does Flex Consumption allow execution of arbitrary ELF64 executables via execve? If not, is this a documented limitation or a bug?
Longer question: Need confirmation whether executing native Linux binaries such as ffprobe/ffmpeg is supported in Flex Consumption. By default the main execution stack is read-only, so the binaries need to be moved "outside" to support a writeable working directory. I am able to do this and it does allow execution, however they immediately segfault. The same binaries work locally in a Linux container. No console access on Flex makes it impossible to debug. Requesting engineering confirmation whether this is supported by design.
This works if I use Windows binaries in a Windows Consumption Plan.
This is a huge gap between the Flex and "Legacy" Windows Consumption Plan. I would like to move to all Flex plans, but this is a significant limitation.
