I agree that snapshots seem like an easy feature to live without during install. Are you saying the relevant patch is in Debian kernels anyway? However, BBR seems trickier. While it used to be a feature, it is now only available as a segment manager to attach to a disk. So it seems to me that if it's not available at install you'll have to use some other segment manager, and will have no good way to change that later. My impression is that modern disks do BBR in hardware, so I'm not sure how important this facility is in practice. I was using it, but it may be redundant. There might be other options I ignored, like high availability or clustering, which also would need to be set up at initial install. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
