Benjamin Bannier commented on MESOS-6182:
-----------------------------------------

Linking MESOS-6011 as an example of tests failing because {{LinuxRootfs::create}} does not create a deterministic rootfs.

> {{LinuxRootfs::create}} attempts to add a hardcoded list of files to the created rootfs. However, if a file does not exist no failure is created, but the file will be missing from the rootfs.
> This can then lead to failures in tests using the rootfs and relying on files in it.
> We should make failures to compose the planned rootfs explicit so users of this test code know what they can rely on.
