[Pkg-ltsp-devel] Bug#771728: ltsp-client-core: hooks in /etc/kernel/postrm.d/ break linux-image package removal on arm

[Vagrant Cascadian]

Package: ltsp-client-core
Version: 5.5.4-1
Severity: serious
Tags: patch

When removing a linux-image package on an armhf system (and presumably
armel as well), mkimage is called in the ltsp-client hook
/etc/kernel/postrm.d/update-kernels, and generates output that causes
the package removal to fail...


Removing symbolic link initrd.img.old
You may need to re-run your boot loader
Purging configuration files for linux-image-3.16.0-4-armmp-lpae (3.16.7-2) ...
dpkg: error processing package linux-image-3.16.0-4-armmp-lpae (--purge):
 subprocess installed post-removal script returned error exit status 128
 Errors were encountered while processing:
  linux-image-3.16.0-4-armmp-lpae

E: Sub-process /usr/bin/dpkg returned an error code (1)

The following patch fixes this by redirecting the mkimage output to
/dev/null.

I plan to upload a fixed package today.
