Package: debootstrap Version: 1.0.114 On a fresh install buster under docker I ran "debootstrap buster test". This lead to a system without /proc mounted.
The following error are found: >> I: Target architecture can be executed >> I: Retrieving InRelease >> I: Checking Release signature >> I: Valid Release signature (key id 6D33866EDD8FFA41C0143AEDDCC9EFBF77E11517) >> I: Retrieving Packages >> I: Validating Packages >> I: Resolving dependencies of required packages... >> I: Resolving dependencies of base packages... >> I: Checking component main on http://deb.debian.org/debian... >> I: Validating libacl1 2.2.53-4 >> I: Validating adduser 3.118 >> I: Validating apt 1.8.2 [...] >> I: Extracting mount... >> I: Extracting util-linux... >> I: Extracting liblzma5... >> I: Extracting zlib1g... >> W: Failure trying to run: chroot "//test" mount -t proc proc /proc >> W: See //test/debootstrap/debootstrap.log for details >> I: Installing core packages... >> I: Unpacking required packages... >> I: Unpacking libacl1:amd64... >> I: Unpacking adduser... [...] In the debootstrap.log I saw: mount: /proc: mount(2) system call failed: Too many levels of symbolic links. It reproduces always, even with different host OS (stretch and gentoo are tested) I have also tried the "testing" version without changes.
