Bug Description

From http://www.kernel.org/doc/menuconfig/drivers-acpi-Kconfig.html:

_Deprecated power /proc/acpi directories_

For backwards compatibility, this option allows
deprecated power /proc/acpi/ directories to exist, even when
they have been replaced by functions in /sys.
The deprecated directories (and their replacements) include:
/proc/acpi/battery/* (/sys/class/power_supply/*)
/proc/acpi/ac_adapter/* (sys/class/power_supply/*)
This option has no effect on /proc/acpi/ directories
and functions, which do not yet exist in /sys
This option, together with the proc directories, will be
deleted in 2.6.39.

Note that Debian's 2.6.39 no longer has /proc/acpi/battery, so byobu battery status is broken on testing and squeeze-backports kernels. Given that the alternative to squeeze-backports is the squeeze 2.6.32 kernel that doesn't support much new hardware released after ~2009 (including video and touchpad on my 2010 Thinkpad laptop; see Debian bug reports), you've left a good bit of the Debian-using population without use of battery status.

  * usr/bin/byobu, usr/lib/byobu/ip_address, usr/share/man/man1/byobu.1:
    - support IP_EXTERNAL fetching, LP: #873736
    - put ip address in the terminal title bar, since we ran out of room
      for it in tmux
  * usr/bin/byobu-select-session: LP: #869390
    - fix select session to obey BYOBU_BACKEND
  * configure.ac, usr/bin/Makefile.am: LP: #869377
    - provide byobu-tmux and byobu-screen symlinks
  * configure.ac, README: LP: #861291
    - configure should not change files under vcs control
    - compiling users need to ensure that BYOBU_PREFIX is set in
      their environment
  * usr/bin/byobu-launcher-install, usr/bin/byobu-launcher-uninstall:
    - LP: #861534
    - ensure launcher command removed from each file before installing
  * usr/lib/byobu/.dirs:
    - use /dev/shm for cache, LP: #872551, #869279
    - search and use a shared dir when possible
  * usr/lib/byobu/battery: LP: #851100
    - rework the battery logic to use /sys instead of /proc
  * usr/share/man/man1/byobu.1: LP: #713879
    - note too many files open ulimit error in documentation

  [ Daniel Hahler ]
  * usr/bin/byobu, usr/bin/byobu-launcher-install, usr/bin/byobu-
    launcher-uninstall: Use BYOBU_PREFIX explicitly, LP: #861302
