The cost of atime is not very dramatic when using zfs except for
perhaps the snapshots issue which was already mentioned. This is
because the atime updates are cached in memory and are only written to
underlying store at the next zfs sync interval. So maybe atime will
be updated in the filesy
Seems like the Linux style O_NOATIME flag (usable only by root - or on Solaris
derivatives, possibly with a fine-grained permission) might be a useful
addition to the OS, so that system programs that read a lot of files can avoid
causing massive time updates that either generate excess I/O and o

I now have a pair of Samsung SSD 980 500GB NVMe M.2 drives as a ZFS
mirror for root on this new machine. It installed straight away with no
dramas.
It boots fast! Wow.
Thank you all for your help and advice, esp Aurelian for the updated USB
image. Any chance OI could do a release of it?

Nice. I have 32 GB, should be enough. Thank you. I'm off to grab a couple of
M.2s and see how they go.
Note that I am using AHCI-mode M.2s (similar to "SATA" but at M.2
speed) which are likely now somewhat rare.

Hi!
Remember that firefox likes if there is plenty of swap configured! It
