...p computer (this one) I would have a ssd installed in it to use for the boot drive. Now that Centos 7 is on the horizon, I'm thinking that the time is approaching when I'll want to do that. The last time I set up a computer with a ssd in it, that was the only drive that it had.

...esystem> Now we start use ssd disk and think how to provide additional options for mount root FS in container: "discard" and "nobarrier" options for XFS. All level below XFS configured for support trim command ("options raid0 devices_discard_performance=Y" and "issue_discards = 1") I try set options inside container in /etc/fstab, it's not worked: /dev/root / rootfs discard,nobarrier,defaults 0 0 or /dev/root / rootfs discard,nobarrier 0 0 or /dev/root / rootfs remount,discard,nobarrier,defaults 0...
