Just a small point, CoW is supposed to be about minimising risk. Until the write is successfully completed, the original info still exists. And it shouldn't be all that often that you're re-writing the same file that you'd notice the tiny amount of extra effort involved in doing that (write the new file, elsewhere, then remove the filesystem pointers to the prior version). Even without CoW many same file rewrites will have to do a similar set of steps: Write the new version of the file, update the filesystem pointers about the different usage of the file storage (new file dates, extra/less blocks that got used as the file changed size). Most computer operations are massively faster than what WE do with the system. The CPU can be doing millions of operations while I'm typing this short email. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
