Comment 2 for bug 1758697

I think the priority would be for any config that is required during the initial creation; other settings can be configured via scripts or other tuning mechanism. The cutoff, for example isn't something curtin should do by default ,rather it's a knob for benchmarking. I'd think the benchmark test would set and clear that as needed.

I think the following config options make sense (creation time settings):

--data-offset <sectors> # defaults to 8k, but could get aligned for RAID backing devices
--cset-uuid <UUID> # maas already sents UUID values for filesystems, it could set these too

Most of the rest can be changed at runtime. We also need to investigate to see if the
bcache sysfs changes are persistent across reboot.

Besides the cutoff setting, are there other tunables that you would find useful to have inplace at install time?
