Gee^^^Wizardly Lore: The Great Dot Mystery and the Coming of the Superfast Minifile

    So I'm trying to find out what and where exactly the "." (pseudo-?) file
    is in my Linux ext2 hard-drive filesystem and how to fix one (I've got one
    that _must_ be oversized, 68K with only two small files in the directory)
    and while I haven't found those first two bits o' elementary information
    explicitly explicated yet I ran across this amazing statement (my caps):

    "Ext2fs implements fast symbolic links. A fast symbolic link does not use
    any data block on the filesystem. The target name is not stored in a data
    block but in the inode itself. This policy can save some disk space (no
    data block needs to be allocated) and speeds up link operations (there is
    no need to read a data block when accessing such a link). Of course, the
    space available in the inode is limited so not every link can be
    implemented as a fast symbolic link. The maximal size of the target name
    in a fast symbolic link is 60 characters. WE PLAN TO EXTEND THIS SCHEME
    TO SMALL FILES IN THE NEAR FUTURE."

    http://web.mit.edu/tytso/www/linux/ext2intro.html

    Get that? storing small files right in their inodes? just the thing for
    all those annoying little one or two-line configuration and other files
    encountered by the kernel as it runs around, like user names and
    passwords, shmall and shmmax, and so on (one could even see a USB buffer
    stuffed in there).

    That was in 1994. I wonder if it's implemented now. Or whether . . .
    something happened . . . .

    And just where _are_ the damned inodes, anyway? I hope there's multiple
    copies of the inode list.

    When a system is set up to accomplish some goal, a
    new entity has come into being--the system itself.
    No matter what the "goal" of the system, it
    immediately begins to exhibit system behavior; that
    is, to act according to the general laws that govern
    the operation of all systems. Now the system itself
    has to be dealt with.

    Ubuntu/Breezy Badger (no longer supported, the bastards, except by a few
    hold-out package-repositories-- the last time I installed a package, it
    was from a repository run by the Malta LUG).

    But I was browsing around for info on the ext2 filesystem.

    As is often the case these days, wikipedia is a good place to start:

    http://en.wikipedia.org/wiki/Symbolic_link
    http://en.wikipedia.org/wiki/Inode

    No need for me to provide urls to other info - the wiki author dudes

    Given a manifold M with a submanifold N, N can be knotted in M
    if there exists an embedding of N in M which is not isotopic to N.
    Traditional knots form the case where N = S1 and M = S3.
