Subject: Divert /sbin/initctl to fix start(8) in lucid postinsts.

Date: Tue, 23 Feb 2010 13:33:28 +1100

Package: pbuilder
Version: 0.196
Severity: normal

pbuilder currently creates a policy-rc.d that prevents daemons from
starting when they are installed to satisfy build dependencies.  This
works well for sysvinit packages.

However, when working with Ubuntu Lucid[0] chroots, many daemons use
upstart instead of sysvinit.  Thus, they ignore policy-rc.d, try (and
fail) to start, further causing the postinst, dpkg, satisfybuildepends
and ultimately the entire pdebuild to fail.

According to CJ Watson of #ubuntu-devel, this can be done by diverting
/sbin/initctl and substituting a stub.  An example of this can be seen
in debootstrap's "gutsy" script (excerpt below).  Please add something
similar, I guess to /usr/lib/pbuilder/pbuilder-modules:mountproc.

        mv "$TARGET/sbin/start-stop-daemon" "$TARGET/sbin/start-stop-daemon.REAL"
        echo \
    "#!/bin/sh
    echo
    echo \"Warning: Fake start-stop-daemon called, doing nothing\"" > "$TARGET/sbin/start-stop-daemon"
        chmod 755 "$TARGET/sbin/start-stop-daemon"

        if [ -x "$TARGET/sbin/initctl" ]; then
          mv "$TARGET/sbin/initctl" "$TARGET/sbin/initctl.REAL"
          echo \
    "#!/bin/sh
    echo
    echo \"Warning: Fake initctl called, doing nothing\"" > "$TARGET/sbin/initctl"
          chmod 755 "$TARGET/sbin/initctl"
        fi

[0] In theory this was an issue with earlier Ubuntu releases, but it
    seems to be far more prevalent in Lucid.

Erm... why not fix upstart to respect policy-rc.d ?

I don't know if it should -- I'm just a lowly sysadmin.  By all means
try to convince the upstart people to support policy-rc.d.  If so,
please retitle and reassign this ticket to upstart.

Hi,

Hmmm..I see a problem. Ubuntu isn't Debian so they can break Debian
policy as much as they wish. Which sucks.

 upstart is in Debian; I'm not sure of why it doesn't honor policy
 checks, I suspect it could be that it would kill boot performance.

FWIW upstart itself is in Debian, but daemons[0] don't support it
out-of-the-box, so this issue doesn't manifest with Debian chroots.
Of course, being able to use Ubuntu chroots on my Debian box is still
desirable -- it avoids needing a separate Ubuntu box :-)

upstart seems to be working fine here in sid these days.  It replaced my
init.  (concurrency seems to be supported by rcS even before installing
upstart though...  I did not look into these issues much.)

If it has such shortcoming, asking it to be fixed in Debian is good
idea.  Then Ubuntu may pick it up.  So far there are not many bugs
filed on upstart.

I agree. This is a bug in upstart, sorry.
I haven't even tried to check whether this is still the issue, but whatever
diversion for this sounds plain wrong.

Control: reassign -1 pbuilder

This bug was reassigned to upstart, but that is not correct.  The problem
described here is that a bug in the version of *debhelper* in Ubuntu Lucid
caused maintainer scripts for packages that shipped upstart jobs to
incorrectly call 'start' instead of the policy-defined 'invoke-rc.d'
interface.  This was a bug in debhelper in an old version of *Ubuntu*. 
There is nothing that the *Debian* *upstart* package can do to work around
this bug.

The bug was filed against pbuilder, as the tool managing the chroots on top
of the Debian system, requesting that 'start' be diverted in order to give
an effect similar to policy-rc.d.  You might close this bug as wontfix, but
it's nothing that the Debian upstart package can help with.

Great.
lucid is EOLed, that version of debhelper even precedes my involvement in
debian, and FWIW it's not even on supported debian releases.

Neither pbuilder, diverting a file like that is not a fix.
