Lastly I renamed sda1 to sdb1 in rc.local and then typed “mount” in telnet to check that the disk had been mounted with “noatime”.
Keep the noatime behaviour in mind. If in the future you install a piece of software that makes use of file timestamps then you might see some odd behaviour.
I haven’t made any edits to the crontab but perhaps I should as I have a feeling the drive might wake up due to the clock being reset every hour? We’ll see.
The slug clock drifts quite a lot. It’s probably worth leaving the hourly synch in there. In fact, if you haven’t done so already there’s an unslung wiki page that explains how to setup ‘ntpclient’ on the slug.
