Re: [tlug] how filesystem works?

I don't think that's all that intuitive because the Unix indirect
directory structure (directory links names to inodes, inodes collect
metadata and information about actual space) is completely unknown to
most users.  I *used* to think that people would go "Link?  Unlink?
WTF?" and go find out why such an odd name made sense.  But these days
even Linux users just don't want to know.

Yeah, this is basically the scheme I use.  However, Linux practice is
a little different:

If you have a devel system, 5GB in /usr is tight for many Linux

Most Linux distros put daemon data in /var, eg, web documents in
/var/www, database data in /var/lib/db-du-jour, and so on.

/home is nosuid.  naruhodo.
