reasoning behind rc.6 telinit change?


Quote:
rc.6: restart init when shutting down - this prevents it from holding file handles to removed/upgraded versions of the glibc shared libraries which would interfere with shutdown.
No issue, I'm just curious about this one. How is init holding file-descriptors for the removed (unlinked) glibc shared libraries any different than it holding file-descriptors for the newer (linked) versions of the libraries during shutdown?

Not sure, but it is. I had wondered if it still made sense to restart init and tested it here... without the restart / fails to remount and gets an fsck on the next boot.

Ahh, of course, the inode still needs to be freed even though its unlinked and I guess that stops the filesystem being mounted read-only. Interesting. Thanks for the reply. I just learnt something.

As did I !

This may explain an odd error I get on a home-brew server application ... off to check it out !

Thanks for asking GazL and thanks for your reply volkerdi !
