[Bug 1332155] Re: debootstrap launches spurious udevd --daemon

[Brian Candler]

Retested with 22.04.3:

/usr/sbin/debootstrap --arch=i386 trusty /tmp/tmpBQAxhc
http://archive.ubuntu.com/ubuntu | strace cat >db.out

This completes successfully. The problem was likely fixed in debootstrap
1.0.52 according to https://bugs.launchpad.net/ubuntu/+source/vm-

Title:
  debootstrap launches spurious udevd --daemon

Status in debootstrap package in Ubuntu:
  Incomplete

Bug description:
  On a 12.04 amd64 system, when running debootstrap to generate a 14.04
  image [i386 or amd64], an instance of "udevd --daemon" is launched and
  persists after debootstrap terminates.

  How to reproduce:

  Freshly booted system. Before:

  # ps www -C udevd
    PID TTY      STAT   TIME COMMAND
    449 ?        Ss     0:00 /sbin/udevd --daemon
    673 ?        S      0:00 /sbin/udevd --daemon
    674 ?        S      0:00 /sbin/udevd --daemon

  Now run the following:

  # /usr/sbin/debootstrap --arch=i386 trusty /tmp/tmpBQAxhc
  http://archive.ubuntu.com/ubuntu

  When it has finished:

  # ps www -C udevd
    PID TTY      STAT   TIME COMMAND
    449 ?        Ss     0:00 /sbin/udevd --daemon
    673 ?        S      0:00 /sbin/udevd --daemon
    674 ?        S      0:00 /sbin/udevd --daemon
  29146 ?        Ss     0:00 udevd --daemon

  Extra tests:
  This *doesn't* happen when building precise i386 on precise.
  It *does* happen when building saucy i386 on precise.
  It *doesn't* happen when building trusty i386 on trusty (tested in a trusty VM)

  Apart from leaking a process, this is the root cause of bug #1287943:
  a process which runs debootstrap in a pipeline to read stdout finds
  that the pipeline is never closed (and therefore never terminates)
  until the udevd --daemon process is manually killed.

  Most likely this is because stdout is passed to that process, which
  doesn't close it.

  Base system is 12.04 fully updated, with the raring enablement stack
  (kernel 3.8.0-42-generic). In a comment in #1287943 they asked me to
