Bug Description

Binary package hint: cron

Ubuntu release: 9.04
Package: cron 3.0pl1-105ubuntu1

The script /etc/cron.daily/standard in cron 3.0pl1-105ubuntu1 doesn't report files in lost+found.

The bug in the script is caused by setting $lost_found variable in a pipeline. The variable is set only in a subshell, so it will always be empty when checked later.

A .debdiff to fix this problem is attached. It also adds ext4 to the list of checked filesystems.

How to reproduce (/boot is ext3 and / is ext4):
# echo test-ext3 > /boot/lost+found/test-ext3
# echo test-ext4 > /lost+found/test-ext4
# /etc/cron.daily/standard

The commands above should produce a report about files in the lost+found directories. With the attached patch both files are listed correctly.

This bug was fixed in the package cron - 3.0pl1-113ubuntu1

cron (3.0pl1-113ubuntu1) maverick; urgency=low

  * Merge from debian unstable. Fixes:
    - LP: #46493 (this should have been fixed way back in 3.0pl1-87, and I
      confirmed it is no longer a problem)
    - LP: #118168 (Debian #79037)
    - LP: #151231 (Debian #155109, #443615)
    - LP: #308341 (Debian #437180)
  * Remaining changes:
    - debian/control:
      + Build-Depends on debhelper >= 7.3.15ubuntu2, for Upstart
      + Drop MTA and lockfile-args to Suggests
    - add debian/cron.upstart
    - debian/postinst: remove calls to update-rc.d, invoke-rc.d and
    - debian/postrm: remove call to update-rc.d
    - debian/prerm: remove calls to invoke-rc.d and /etc/init.d/cron
    - debian/rules: install Upstart job
  * Drop the following changes, now in debian:
    - popen.c: check return code of initgroups() in cron_popen()
    - debian/control: add missing ${misc:Depends}
    - debian/control: Depends bump on lsb to >= 3.2.12ubuntu2. No longer
      required now that we use Upstart
    - debian/cron.pam: switch from including common-session to including
      the new common-session-noninteractive
    - pathnames.h: use sensible-editor

cron (3.0pl1-113) unstable; urgency=medium

  [ Christian Kastner / Javier Fernandez-Sanguino ]
  * debian/postinst:
    - Now that permissions and ownership of crontabs are changed unconditionally,
      do not attempt to chown user crontabs if none are present. Closes: #585636
    - Only change permissions if the crontabs directory exist

cron (3.0pl1-112) unstable; urgency=low

  [ Christian Kastner ]
  * do_command.c:
    - Don't send mail when a job exits non-zero, only send mail if the job sent
      output to stderr. This behaviour was introduced erroneously; while it
      does have merit, it is completly against standard cron behaviour.
      Closes: #581612
  * debian/compat:
    - Bumped debhelper compatibility to 7
  * debian/control:
    - Bumped Standards-Version to 3.8.4 (no change needed)
    - Build-Depend on debhelper (>= 7.0.50~)
    - Added dependency on ${misc:Depends} to package cron
  * debian/cron.init:
    - Changed Default-Stop from (1) to (empty). rc0 and rc6 were removed in
      3.0pl1-101 because the stop action -- sending SIGTERM/SIGKILL to cron
      on shutdown/reboot -- was redundant. This, however, also applies to
      rc1, because killprocs will do that for us.
  * debian/postinst:
    - Removed obsolete dpkg file backup code, this has been handed over to dpkg
      in 3.0pl1-109
    - Removed last remaining stop action (for rc1) from upate-rc.d (see above)
    - Add dpkg-statoverride for /usr/bin/crontab, and unconditionally change
      permissions of /var/spool/cron/crontabs. Closes: #304036, #460095
  * debian/standard.monthly:
    - Removed because it had been empty for years and therefore served no
  * debian/cron.bug-{control,script}
    - Added to extend information submitted by reportbug
  * debian/rules:
    - Applied changes for standard.monthly and cron.bug-{control,script} above
  * debian/copyright:
    - Updated to reflect recent contribution...
