[DTrace-devel] [PATCH] dtprobed: make sure the daemon is started in the first place

[Nick Alcock]

The work done earlier only suffices to restart the daemon automatically on
upgrade.  There appears to be no attempt to start newly-installed daemons at
a distro level, only to enable them (via presets).  Most daemons already in
the distro don't bother, apparently relying on the post-installation reboot
to start them.

We'd rather do the job right, so explicitly do a start in %posttrans (which
it looks like will usually be late enough that the thing will already have
been enabled even if presets don't do the job -- we have no way of running
later other than hooking into at jobs or something, at any rate.)
