# The use of sensitive environment variables, such as LD_PRELOAD, is disallowed
# when init is executing other binaries. The use of LD_PRELOAD for init spawned
# services is generally considered a no-no, as it injects libraries which the
# binary was not expecting. This is especially problematic for APEXes. The use
# of LD_PRELOAD via APEXes is a layering violation, and inappropriately loads
# code into a process which wasn't expecting that code, with potentially
# unexpected side effects. (b/140789528)
