Sorry. I should ask that another way. If subvolumes are that great, why aren't all the subdirectories of / subvolumes? "/etc" for example. Why not "/bin" and "/lib"?
And why aren't there any secondary subvolumes, since that's not prohibited, things like "/usr/lib" which is pretty large, and "/usr/doc"?
Because it is not necessary, and there is a penalty. I mentioned regressing an update via booting to an older snapshot. In this case, it is needed to revert changes in many places, like bin and lib and etc and /usr/lib, but not in /var/log, for instance. Or the journal directory. Perhaps not the data directories in root. I haven't studied the details, I'm not that interested. But the thing is, there are many directories that are treated equally, so no need to have them in separate subvolumes. Only those in which you need to do something different are made a subvolume. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
