Nobody creates /lib/init/rw/sendsigs.omit.d

[Patrick J. LoPresti]

Binary package hint: sysvinit

Release: lucid
Version: 2.87dsf-4ubuntu17

/etc/init.d/sendsigs reads the /lib/init/rw/sendsigs.omit.d directory for a list of files containing PIDs to omit when killing all processes during shutdown/reboot.

Some init scripts (e.g., open-iscsi and wpa-ifupdown) attempt to use this directory to protect themselves from being killed.

But on a stock Lucid system, nobody creates this directory. Consequently, there are problems. For example, any system using open-iscsi is unable to shut down or reboot:

This is clearly a bug in the initscripts package. Since the "sendsigs" script is the only consumer of the /lib/init/rw/sendsigs.omit.d directory, it ought to be responsible for creating it; or at least, some other mechanism in the initscripts package should be responsible for doing so.

Addendum:

I changed my mind; this is not necessarily a bug in initscripts. It could be a bug in "mountall", which creates sendsigs.omit.d under /var/run:

https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/604137

The bug is that the various init scripts are not in agreement. Please make up your minds where the sendsigs.omit.d directory belongs and then fix all init scripts to be consistent about it. Until then, anybody using open-iscsi cannot even reboot their systems. Thanks.

I think this is just the same as bug 541512. I've reassigned the latter to sysvinit, and will mark this as a duplicate and fix it.
