   cp enabling copy-on-write by default is a _huge_ performance boost for things like "make install"... but only for those using #xfs, #btrfs and perhaps also F2FS.

     @kai @benoit I've been using XFS filesystems formatted with the reflink option when it was still experimental. It's been enabled by default on newly formatted filesystems for a few years.

     One case where I use it is for making backups of configs before launching a new beta, so I can safely rollback:

     cp -a --reflink ~/.config/chromium ~/config/chromium.bak
