Title:
  syslog messages truncated to 256 chars during debian-installer run

Status in BusyBox:
  Unknown
Status in “busybox” package in Ubuntu:
  In Progress
Status in “busybox” source package in Precise:
  In Progress

Bug description:
  [Impact]
  Users relying on busybox within their environment and attempting to do any sort of debugging of logs.

  [Test Case]
  Run the installer, parse logs from syslogd packaged within busybox.

  [Regression]
  Minimal, only doubling buffer size for syslogd within busybox.

  
  We're seeing syslog messages during installers runs truncated to 256 chars. This is annoying.

  Digging into the debian-installer source, its calling /sbin/syslogd
  from the initrd - this is a busybox binary. In the busybox source,
  there's a config variable CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE that
  defaults to 256. From the code, that looks to be the problem.

  Can we either -
  1. fix busybox to use a dynamic buffer, or
  2. bump the config variable up to 1024 or so?

  I'm perfectly happy with solution 2 :)
