Disappointed in the response over at Ubuntu: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1729836 https://bugs.launchpad.net/ubuntu/+source/in

  This isn't an initramfs-tools bug–if you're LD_PRELOADing into a binary, presumably you know what you're doing. The "bug" here is setting LD_PRELOAD as root (if accidentally through sudo -s) and running a sensitive operation, knowing full well that stderred is a (admittedly very useful, since I use it!) hack at best.

    I suggest that it actually is an initramfs-tools bug. As pointed out elsewhere in this very discussion, the program in question must be using file descriptor #2 as its output file descriptor for the files that get corrupted, because stderred only inserts its hardwired control sequences on writes to that file descriptor. That's a bad thing to be doing independent of stderred, because there is potentially other (library) code in the relevant program (whatever it is) that assumes that file descriptor #2 is usable for diagnostics. Even without stderred in the mix, it is a bug waiting to be triggered via another route.
