Bug#383600: behaviour of update-initramfs -u has changed, only updates latest kernel initrd

I think this means
update_initramfs=all
.

Is that correct?

Neither the comments in that file nor the man page list "all" as a legal
option.  It would be good to update them if it is.

I too noticed this issue when updating udev while running an older
kernel than the most recent one installed.  I find the current behavior
surprising, and it doesn't strike me as necessarily more conservative.
It's safer if update-initramfs or something else makes the initramfs
broken.  But it's less safe if it fails to apply a security fix or a
necessary component (e.g., if you install evms any initramfs from before
the installation will not work; evms uses update-initramfs -u in its
postinst).

As long as there's some way to change the default, I guess everyone can
have their own opinions :)
