nscd: Improve nscd.conf comments.
|
||
|
|
|
||
|
|
This change adds a warning to nscd.conf about running multiple caching
|
||
|
|
services together and that it may lead to unexpected behaviours. Also we
|
||
|
|
add a note that enabling the 'shared' option will cause cache hit rates
|
||
|
|
to be misreported (a side effect of the implementation).
|
||
|
|
|
||
|
|
v2
|
||
|
|
- Rewrite comment to avoid implementation details.
