Things seem to be getting worse. I originally discovered the problem
because a routine upgrade of procps failed because it could not make a
link to /bin/ps. I eventually found that it was due to the "i" flag on
that file. I removed the flag and it then worked. However, last night I
found that the flag had returned. I removed it again. 

Today, I found that upgrading procps failed again, this time because it
was unable to create /bin/kill. But /bin/kill does not have the "i" flag
set. So it definitely seems that something strange is happening.
