Used on some UNIX systems by System Admins. A special directory is created callled WGAS. Any file(s) where the owner no longer has an account and takes up excess
space is placed here. If nobody asks about the missing file for a month or so, the file(s) is deleted. If someone really does care that a file is missing, then it is moved back in place. It's one way of keeping the system
free of
junk.
There was one system I became the admin of where it was cluttered by logs and report programs. The system was running
low on hard drive
space so I began asking about the reports. No one knew about them so I move the report programs and the logs into the WGAS directory. After
two months nobody complained so I removed them.
The system freed up a few Inodes and I never heard a complaint from anyone. The system has since been replaced.
