I had the opportunity (read: crash) to restore from a backup, after re-installing the OS from distributions (2.0.5R). I noticed that a lot of programs weren't running any more: looking at them with file was giving me "data" instead of the "FreeBSD/i386 demand paged dynamically linked executable not stripped" I was expecting. I am slowly reinstalling/ recompiling the programs group by group. It seemed to me that somehow the files were not restored properly: the beginning of the file had extra cruft and there was data missing from the end. It also happened to text files, so it is not strictly binaries that were affected. Weird. I am going to use dump from now on to backup the system (restructured the filesystem to only have a root and usr f/s), so this is really just a lessons learned for me and a warning for the rest of us. -- "Voom?
