The only file-system switch I know well is that
in the later Research
systems. It has nothing to do with disks or blocks. It is about names
and inodes: turn name to struct inode, read arbitrary chunk of data,
write arbitrary chunk of data, create file, unlink file, abominable
ill-defined system call that just wouldn't die erm I mean ioctl, and so
on.
Ioctl: the Swiss Army knife of system calls. I thought it was a neat idea
when it arrived (much better then those primitive stty/gtty calls) but
now...
