I have moved an executable binary into /usr/bin. This worked, allowing me to run the program as expected.
However, after the next reboot, I noticed the command did not respond, and when I checked /usr/bin the file was no longer in it. Something has deleted it.
I tested it several times, and tried symbolic links as well. The same effect occured.
I remember similar behaviour on a Fedora Core 5 box, when I had a file in one of these paths, and everytime I replaced it with a newer version, the older version reappeared after a while. Something backed up the file and did not allow me to change it. It did allow me to delete it later.
Similar behaviour on two systems. The current computer is a Thecus RAID box running Linux.
What is going on?
How do I place or replace these files so they stay where I put them?
