I guess the bug has been present for a longer time, so please update the version information accordingly.

Dear maintainers of init-system-helpers, please consider following
patch, that adjust behaviour of update-rc.d to match manpage.

If this bug is ever fixed, please make sure that '-f' still allows the
symlinks to be removed.

Currently the only way to restore the symlinks to the defaults specified
by the initscript are 'remove' followed by 'defaults' because the
'defaults' operation, inexplicably to me, won't set the defaults unless
there are no symlinks at all.

#339460 is marked as WONTFIX and #731905 doesn't seem to think this
situtation ('defaults' not doing anything useful for an
already-installed script) is a problem so presumably the behaviour of 'defaults' isn't ever going to change, so let's at least make sure
'remove -f' remains to let users and maintscripts do a forcible revert
to defaults when required.

Thanks!

As I understand it, the reason for this is that maintainer scripts do `update-rc.d scriptname defaults`, and that should preserve sysadmin
removals of symlinks (because the syadmin doesn't want something to
run).

The *current* convention (which bends the rules about preserving
sysadmin changes but in a way that kinda works for people) is that if
you remove just `S` symlinks but leave the `K` symlinks you can prevent something from starting, but if you remove *all* the symlinks then
`defaults` will reinstall them.
