Btrfs devel - Feb 2011 - [Fwd: Re: Suggestion for sticky-compression mount setting (default mount options)]

forwarded message below:


It would be very iseful.
I also propose the same for `-o ssd` option. USB drive may be used on different
computers, and we need the way to specify it only once.
As for the options being per-file, I think having them as per subvolume defaults
looks better: we can override the defaults on per-file basis while having
reasonable defaults for each subvolume. (There may be also global per-pool
defaults, which may be overriden by subvolumes).

I think that if the file is compressed it should remain compressed and the
"c"
attr should be used for that (both to report it and to set it).

There should be a way to specify *which* type of compression to use in a 
sticky way, system wide and whatever to compress newly created files also 
''-o ssd'' definitely should go in the same basket.
