new functionality in glibc: the nscd (name service cache daemon) can now maintain a persistent cache which is not unconditionally removed when the program is restarted or the system reboots. Entries are not removed from the cache until they are proved to be of no interest anymore. All entries which expires time-to-live which are still interesting are automatically reloaded. This helps in situations where the directory and name services become temporarily unavailable.
Ulrich -- thanks for submitting this; how does this sound: The nscd name service cache daemon now maintains a persistent cache across restarts or system reboots. Entries are not removed from the cache until they are proven to be no longer of interest. All entries whose time-to-live expires but are otherwise interesting are automatically reloaded, which helps in situations where the directory and name services become temporarily unavailable.
Fine with me.
Super -- thanks for the quick feedback! Added...
Reading the text again, it might be a bid misleading. The persistent mode is optional and if the user updates an existing system the mode might not be enabled by default. How about <<< The nscd name service cache daemon may now maintain a persistent cache across restarts or system reboots. Each database (user, group, and host respectively) can be made selected to be persistent by setting the appropriate line in /etc/nscd.conf to yes. Entries are not removed from the cache until they are proven to be no longer of interest. All entries whose time-to-live expires but are otherwise interesting are automatically reloaded, which helps in situations where the directory and name services become temporarily unavailable. >>> And one more thanig: we have a second improvement in nscd which is worth noting since it might need to be enabled. Perhaps a paragraph like: <<< The nscd version in FC3 is also able to communicate faster with the client programs. This feature needs to be enable explicitly by setting the "shared" entry for the appropriate database in /etc/nscd.conf to "yes". >>>
Done.
