From: Martin Johnson on 24 Apr 2010 09:37 Is 'make installworld' safe in multi-user mode, if the only service running is my SSH session? Or will something get corrupted when it tries to update the running SSH binary + libs? Thanks! - Martin

Can't say that it's guaranteed safe, just that I've been doing it that way for years without problems. -- Warren Block * Rapid City, South Dakota * USA

Thanks! That's useful to know. - Martin

Certainly nothing will get corrupted the open filehandle will ensure that running programs see the old versions and only new opens will see the new files. For this reason you will want to reboot afterwards (or at least drop to single user and back) in order to ensure that no old code is running. I am curious as to why you would want to installworld multi-user given that after updating sources it is potentially necessary to install the new kernel before attempting to run the new world so there is a natural point to pause in single user mode to run installworld. -- Steve O'Hara-Smith | Directable Mirror Arrays C:>WIN | A better way to focus the sun The computer obeys and wins. | licences available see You lose and Bill collects. | http://www.sohara.org/

I won't reply for Martin, but in my case the reason is: remote make/build/install. I'm not sure you can SSH to a FreeBSD box that is booted in single user... patpro -- A vendre ! http://www.patpro.net/blog/index.php/2008/01/12/133 |
