I bet this is due to removing the busybox hook from initramfs-tools
itself.
The ordering of initramfs-tools hooks is firstly ordered by
dependencies, but secondly by name (not documented, but implicit in the
implementation).
We used to run hooks in this order:
1. busybox (initramfs-tools)
2. klibc (initramfs-tools)
busybox version 1:1.21.0-2exp changed the order to:
1. busybox (initramfs-tools)
2. klibc (initramfs-tools)
3. zz-busbyox (busybox)
initramfs-toools version 0.123 changed the order to:
1. klibc (klibc-utils)
2. zz-busybox (busybox)
Each of the hooks generally avoids overwriting anything in /bin, so
where both busybox and klibc-utils provide the same command we used to
favour busybox and now we favour klibc-utils. This didn't make much
difference in practice until I made this config change in busybox.
Since initramfs-tools only allows hook A to declare a dependency on
(must run after) hook B, not to declare that it must run before hook B,
this has to be solved in klibc.
