The problem is that /lib/plymouth/label.so now transitively links to
libGL, which lives in /usr/lib/mesa/libGL.so.1 or some other
subdirectory of /usr/lib depending on the GL implementation in use
(fglrx, nvidia, etc.). This directory isn't on the linker's default
search path; instead, it relies on /etc/ld.so.cache having been built
appropriately from a configuration including /etc/ld.so.conf.d/GL.conf,
which is managed by update-alternatives. The thing that's going wrong
here is that /usr/lib/mesa/libGL.so.1 is copied into the initramfs, but
it isn't on the linker's search path so /lib/plymouth/label.so fails to
load.
I looked at fixing this by copying in /etc/ld.so.conf* and running
ldconfig, but this turned out to be very difficult due to the way
mkinitramfs symlinks libraries during initramfs creation. I think it's
better to have copy_exec check whether the target directory name is only
on the linker search path by virtue of /etc/ld.so.conf*, and if so,
install to /lib or /usr/lib as appropriate instead.
