MAKEDEV is in /sbin and is a shell script (text file) that creates
device nodes in /dev
There is /usr/share/doc/makedev that has a changelog and copyright file.
Do these files still exist where they should?
If you can run that binary, run it as --help or -h. If that doesn't
tell you what it is, try viewing ith with mc's viewer and search for
english phrases (things like built-in error messages); try searching for
"usage".
What this all means is that while e2fsck has fixed the filesystem so
that it is consistant and mountable, in the process you have lost files.
The problem is that unless you're running something like samhain or
tripwire you won't know exactly what has changed. This is one reason
that I run samhain.
Its also why I switched from ext3 to JFS.
In any event, unless you can track everything down, be prepared for a
reinstall. In fact, I would plan ahead for one: ensure that you create
a new full backup of your data and DO NOT overwrite your most recent
backup prior to this corruption. Your system may run for some time
until a missing or corrupted file needs to be accessed then BOOM. So
plan for it. You could even take the time now to make a custom CD
(using debian-cd) of all the packages that you have installed so that
the reinstall only takes 20 minutes or so.
Good luck.
Doug.
