Title:
  live Installer may rotate syslog during install and copy only a
  portion to /target/var/log/installer/syslog

Status in ubiquity package in Ubuntu:
  Incomplete
Status in ubiquity source package in Precise:
  Triaged

Bug description:
  The Ubuntu Live CD includes the sysklogd package, which is used for
  logging the install to /var/log/syslog.  The syslog is copied to
  /target/var/log/installer/syslog at the end of installation.  The
  sysklogd package installs a syslog rotation script into
  /etc/cron.weekly/sysklogd which runs at 6:47 AM on Sunday.  If an
  install happens to span across this time, then the log gets rotated
  during the install.  As a result, the syslog that gets copied to
  /target/var/log/installer/syslog doesn't contain the entire installer
  log.

  I'm seeing this in the intrepid installer.  It may exist in previous
  versions, but I didn't check.  I'm not certain what component to file
  the bug under, since  it's a file from the sysklogd package that's
  causing the problem, but the problem is specific only to the install
  cd.

  To reproduce, run an install when the computer's clock is going to
  pass 6:47 AM on a sunday morning and observe the log file after the
  install finishes.  One would expect the see the entire installer log,
  but in fact only sees the portion that occured after log rotation.

  I propose that the live cd either does not rotate logs, or that log
  rotation be disabled during an installation.

  TEST CASE
  1) Boot Live CD to Try Ubuntu
  2) Adjust Date one day into the future
  3) Execute 'sudo /etc/cron.daily/logrotate'
  4) Observe 2 syslog files in /var/log/
