[Buildroot] [PATCH] bluez5_utils: Make systemd link correctly

[Trent Piepho]

The link in /etc/systemd/system/, named dbus-org.bluez.service, pointing to
../../../../usr/lib/systemd/system/bluetooth.service has one too many ".." in
it.  Likely the target was copied from the other link in
/etc/systemd/system/bluetooth.target.wants/, which is one level deeper.

Adjust link to be correct.

However, this should not have any real problem on the target: this
succession of '..' will eventually reach / which has its own '..'
pointing back to itself; that is /.. points to / and so everything
should just work as expected. Only on the build machine does that have
an impact.

So, can you confirm that this is not fixing any runtime issue, but just
making the symlink "less incorrect"?

Regards,
Yann E. MORIN.

Yes, it works on the target fs as the link bottoms out at /.  It just
breaks on the build machine to look at the file or if one runs a script
looking for broken symlinks after discovering all the *.wants links are
broken...
