Restrict file access to append only
I have a directory with log files and I’m putting
logs from script launched by users into them. Logging with syslog doesn’t seem
possible in this case. (non-daemon rsync)

Does any file system implement Copy on Write mechanism for CP?
We have seen OS doing Copy on Write optimisation when forking a process. Reason being that most of the time fork is preceded by exec, so we don’t want to incur the cost of page allocations and copying the data from the caller address space unnecessarily.
