Bug#568261: live-helper: union-filesystem option is ignored

[Andrew Brampton <a.brampton@lancaster.ac.uk>]

Package: live-helper
Version: 2.0~a3-1
Severity: normal


I am building a live CD with a custom kernel (built from kernel.org sources). The problem I'm finding is that I configure my live CD with:
lh config --union-filesystem unionfs

which should imply I want to use the unionfs module instead of aufs. However, while booting the resulting binary.iso I get a error about not being able to mount a aufs file system. This is clearly not possible because I didn't compile my kernel with aufs and instead compiled it with unionfs.

I checked in the file config/chroot and there is a line which says:
LH_UNION_FILESYSTEM="unionfs"

So I suspect the LH scripts are ignoring/overriding this value.

Here are the other parameters I am passing to lh config:
lh config --bootappend-live  "locale=en_GB.UTF-8 keyb=uk" --mirror-bootstrap "$(APTREPO)" --mirror-chroot "$(APTREPO)"
lh config --distribution lenny --hostname vrouter-live --username root
lh config --packages "$(INSTALLPKG2)" --union-filesystem unionfs --linux-packages=none

thanks
Andrew
