Bug#339089: initramfs-tools: delay rootfs-type check

[David Härdeman <david@2gen.com>]

Package: initramfs-tools
Severity: wishlist

Currently /usr/share/initramfs-tools/scripts/local checks for the 
presence of the root device node after local-top has been run but before 
local-premount has been run an panics if it can't find it:

# Get the root filesystem type
if [ ! -e "${ROOT}" ]; then
	panic "ALERT!  ${ROOT} does not exist.  
	Dropping to a shell!"
fi
eval $(fstype < ${ROOT})

This seems a bit counter-intuitive as one would expect a dir called 
"premount" to be run before doing the rootfs checks, so maybe the test 
could be moved down to be just below local-premount instead of below 
local-top invocation?

If rootfstype might be needed in premount, how about setting FSTYPE to 
undefined instead of a panic and delaying the panic to after 
local-premount?
