[Pkg-sysvinit-devel] Bug#588868: sysv-rc: update-rc.d should support empty Default-Start

[Thue Janus Kristensen]

Package: sysv-rc
Version: 2.88dsf-11
Severity: important

I have a backup script on my desktop PC, which should run only on system shutdown (runlevel 0).

So I have written /etc/init.d/backup-thuehome.sh , with an LSB header including
# Default-Start:     
# Default-Stop:      0

But when I try to use it, it fails because the init system won't
accept an empty Default-Start. For example running update-rc.d with an
empty Default-State, or removing Default-Start completely, gives me:

t at h ~> sudo update-rc.d backup-thuehome.sh enable
update-rc.d: using dependency based boot sequencing
update-rc.d: error: backup-thuehome.sh Default-Start contains no runlevels, aborting.

Even worse, when manually adding a symlink to /etc/rc0.d , then the
script silently refuses to run, without an error being logged to
syslog or the console! (this part is why I added the important
severity. Error handling feedback is very important!)

My init scipt works fine if a add for example
# Default-Start:    3

Regards Thue
