NOTES
You're not support to divert Upstart scripts http://upstart.ubuntu.com/cookbook/#symbolic-links-don-t-work-in-etc-init because symlinks aren't supposed to work. In reality, they do work, they just break inotify. The end result is that depending on how the file is moved out of the way, upstart may notice and decide to disable the job. In reality, so far it seems to work, but this snippet in the postinst (AFTER the #DEBHELPER# tag, so it runs after c-p-d) should DTRT:
if ! status lightdm >/dev/null 2>&1; then # I hope this doesn't break the world. initctl reload-configuration fi
A brief discussion of the debconf-hack feature
Primarily developed for zephyr-config to workaround the bug where you choose to use Hesiod (or have DEBIAN_FRONTEND=noninteractive), it pulls in an unconfigured Hesiod, tries to restart zhm, which can't contact any zephyr servers, and exits non-zero, so the postinst fails.
$ cat debathena-zephyr-config.debconf-hack zephyr-clients zephyr-clients/read_conf boolean true zephyr-clients zephyr-clients/need-servers note zephyr-clients zephyr-clients/servers string z1.mit.edu z2.mit.edu
This snippet (from debconf-hack.sh) is added the the postinst, postrm, and preinst.
debconf_get () { perl -MDebconf::Db -MDebconf::Question -e ' Debconf::Db->load(readonly => "true"); for $label (@ARGV) { if ($q = Debconf::Question->get($label)) { print $q->owners."\t".$q->name."\t".$q->type."\t".$q->value."\t".$q->flag("seen")."\n"; } else { print "\t$label\t\t\tfalse\n"; } }' -- "$@" } debconf_set () { perl -MDebconf::Db -MDebconf::Template -MDebconf::Question -e ' Debconf::Db->load; while (<>) { chomp; ($owners, $label, $type, $value, $seen) = split("\t"); @o{split(", ", $owners)} = (); unless ($t = Debconf::Template->get($label)) { next unless ($owners); $t = Debconf::Template->new($label, $owners[0], $type); $t->description("Dummy template"); $t->extended_description("This is a fake template used to pre-seed the debconf database. If you are seeing this, something is probably wrong."); } @to{split(", ", $t->owners)} = (); map { $t->addowner($_) unless exists $to{$_}; } keys %o; map { $t->removeowner($_) unless exists $o{$_}; } keys %to; next unless ($q = Debconf::Question->get($label)); $q->value($value); $q->flag("seen", $seen); @qo{split(", ", $q->owners)} = (); map { $q->addowner($_) unless exists $qo{$_}; } keys %o; map { $q->removeowner($_) unless exists $o{$_}; } keys %qo; } Debconf::Db->save;' }
And then the postinst and postrm have:
if [ -f /var/cache/debathena-zephyr-config.debconf-save ]; then debconf_set </var/cache/debathena-zephyr-config.debconf-save rm -f /var/cache/debathena-zephyr-config.debconf-save fi
The preinst has:
if [ ! -f /var/cache/debathena-zephyr-config.debconf-save ]; then debconf_get zephyr-clients/read_conf zephyr-clients/need-servers zephyr-clients/servers >/var/cache/debathena-zephyr-config.debconf-save debconf_set <<EOF zephyr-clients zephyr-clients/read_conf boolean true true zephyr-clients zephyr-clients/need-servers note true zephyr-clients zephyr-clients/servers string z1.mit.edu z2.mit.edu true EOF fi
