As long as the "defaults" is the first. Because it reads them in order, got it.
I didn't think about that.
So I thought you were right.
But you weren't. Even if "defaults" isn't the first option given, it won't
override earlier options. To test it I just changed the /etc/fstab
entry for one of my data partitions from
LABEL=Data /home/erik/Data1 ext4 defaults 1 2
LABEL=Data /home/erik/Data1 ext4 ro,defaults 1 2
So "defaults" comes after "ro" and should override it. But after a reboot /etc/mtab
still reports the partition as read-only.
It seems that even when "defaults" isn't just used as a placeholder, it isn't a real option either.
hmm, see that did originally make sense to me because in my soon-to-be-former line of work as an e-learn developer, in our dev tools you can put in multiple actions for an object that may seem contradictory but they are read in order so the end result is what you want.
what you are saying here now, is "defaults" is just a placeholder. I am wondering where the real default values are coming from. For instance, they are saying that in the latest linux systems, "noatime" is the default. Where is that being made the default, kernel level?
UPDATE Interesting discussion aside, testing out options and their placement in fstab (with an amusing aside into using "user" on my / drive doh) I have found it doesn't make any difference where I place things.
Additionally, trim is not working. Using the test http://techgage.com/article/enabling_and_testing_ssd_trim_support_under_linux/
I find the garbage is still located there even after removing the file (and used sync) and now have to wonder if indeed it is because this mobo does not support AHCI. It is supposedly a fallacy that you need AHCI for trim as it is a function of the device and the OS. http://forum-en.msi.com/faq/article/ide-sata-and-ahci-all-you-need-to-know
Oh really? Then why is it not working.
Afraid this SSD will meet a bad end in my hands. Three hard shutdowns with no fsck because I don't know what options are safe to use on an SSD. Getting filled with garbage because I possibly have the wrong mobo. I want to start over but afraid to format the darn thing. This was like buying a Porsche when you don't know how to drive. Time to put it on ebay and drag out my trusty old clunk and chunk PATA WD that even I have not managed to kill in years.
