[Bug 1451797] Re: rc.local should require network-online.target

 

While I agree that this may never have been guaranteed, it has been
working with all previous init systems. For me, the implied policy of
using rc.local is: Run after all other init stuff has finished.

For example, https://github.com/puppetlabs/razor-server uses modifying
rc.local in order to trigger some post installation actions to happen
once the node has rebooted after being installed. This works pretty well
with Precise and Trusty and also seems to be fine with most other
distros.

Also, having a server with no network connectivity ever will also not be
very useful. This is certainly different for desktop systems, but then,
why would you have the

After=network.target

at all?

Title:
  rc.local should require network-online.target

Status in systemd package in Ubuntu:
  New

Bug description:
  The current definition in `/lib/systemd/system/rc-local.service` uses
  `After=network.target`, which is pretty useless, as `network.target`
  according to
  http://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/ only
  has relevance during shutdown, which never happens for rc.local.

  The result is that tasks in rc.local may get started before the
  network is properly setup, which may cause them to fail, as this is a
  significant change from the old SysV init behaviour.

  The solution would be to change the dependency to

  Wants=network-online.target
  After=network-online.target

  see also the notes in
  http://www.freedesktop.org/software/systemd/man/systemd.special.html
  for that.
