Subject: [PATCH] core: reinstate propagation of stop/restart jobs via
|
|
|
b48b43 |
RequsiteOf dependencies
|
|
|
b48b43 |
|
|
|
b48b43 |
This reverts the primary effect of be7d9ff730cb88d7c6a869dd5c47754c78ceaef2.
|

|

After all Requisite= should be close to Requires=, without the one
|
|
|
b48b43 |
exception that it doesn't pull in dependencies on start. However,
|
|
|
b48b43 |
reverse deps on stop/restart should be treated the same way as for
|
|
|
b48b43 |
Restart=, and this is already documented in the man page, hence stick to
|
|
|
b48b43 |
it.

|

b48b43 |
and hence we don't have UNIT_REQUISITE_OF. Note that this patch was
|
|
|
b48b43 |
backported because it makes backports of followup patches easier]
