Package: busybox
Version: 1:1.9.1-3
Severity: important

CC'ing initramfs-tools maintainer, as it directly affects hooks into 
initramfs-tools.

BusyBox 1.1.3 implemented a fallback to its own applets in case no 
executable could be found:

	BusyBox v1.1.3 (Debian 1:1.1.3-5) Built-in shell (ash)
	Enter 'help' for a list of built-in commands.
	
	~ $ printf "foo\n"
	foo
	~ $ PATH=
	~ $ export PATH
	~ $ printf "foo\n"
	foo

while BusyBox 1.9.1 just throws an error

	BusyBox v1.9.1 (2008-03-22 22:06:19 UTC) built-in shell (ash)
	Enter 'help' for a list of built-in commands.
	
	~ $ printf "foo\n"
	foo
	~ $ PATH=
	~ $ export PATH
	~ $ printf "foo\n"
	ash: printf: not found

Even though this behaviour is understandable, it does break hooks into 
current initramfs-tools making use of functionality neither provided by 
klibc nor busybox built-ins (but only as applets for busybox), because 
initramfs-tools doesn't create {hard,sym}links to busybox (#338405).

Potentially affected packages (not checked in depths):
- bootcd-mkinitramfs (it seems to use grep)
- cryptsetup (it does use basename #466240 and seems to use grep)
- evms (it seems to use grep)
- initramfs-tools (it does use printf and seems to use awk as well)
- live-initramfs (it seems to use awk, basename, grep and printf)
- loop-aes-utils (it seems to use grep)
- ltsp-client-core (it seems to use grep
- mdadm (it seems to use grep)
- nbd-client (it seems to use grep)
- splashy (it seems to use grep)
- uswsusp (it seems to use grep)

A workaround seems to be enabling 
	CONFIG_FEATURE_PREFER_APPLETS=y
	CONFIG_FEATURE_SH_STANDALONE=y
FEATURE_SH_STANDALONE was enabled in busybox 1.1.3, even though it prefers
busybox applets in favour of shipped executables (unless called with full 
path names), it might be needed until a better long term solution can be found.
