The lost+found directory was a tjk-ism although I can get a very small
level of credit/inspiration. It was born of need. Ted was explaining to
me one night that one of the issues when you had identified a file that no
directory was claiming was what to do with it. Originally, Ted linked lost
files into root because there was usually only a couple of files, but ...
we startiong seeing a situation where often the root directory did not have
free directory slots.
Some of the folks (I want to say it was either bio-med or architecture
dept) had a recurring crash that occurred after a bunch of intermediate
files had been created on a long running program. If the program stopped
we had a way of restarting it part way using them. The problem was that
people did not clean up the /tmp directory so the program unlinked them
after creating them. But if it crashed, the files were still there but
just connected to anything. Ted could find them with f*ck [it had a
different name then].
I remember that we talked more about the issue and he came up with the idea
of creating the directory lost+found and then preallocating a bunch of
slots with a shell script instead of hoping the root directory was going to
being available.
