General Unix Finally something really interesting to talk about. If you've used UNIX or any of its derivatives, you've probably wondered why there's /bin, /sbin, /usr/bin, /usr/sbin in the file system. You may even have a rationalisation for the existence of each and every one of these directories. The thing is, though - all these rationalisations were thought up after these directories were created. As it turns out, the real reasoning is pretty damn straightforward.

RE[3]: why not / instead of /usr

Member since:

"It would make more sense to move everything from /usr to /, then the other direction.

The idea is that you can snapshot /usr seperately from /var, /etc, /boot, etc.

If /boot, /var, /home, and /usr are separate filesystems, then it means that / is also a separate filesystem. Why would snapshotting one filesystem be easier than snapshotting another filesystem? And why wouldn't you want to snapshot the application configuration files along with the applications (meaning, /etc along with apps under /)?
