in reply to perl binary size reducing

In case a programm/person is modifying the compiled perl script, you can try to set it immutable: 
chattr +i mycompiledscript
Afterwards it will not be possible to modify or replace this script until someone executes: 
chattr -i mycompiledscript
Since most programms don't do a 'chattr -i file' before trying to modify a file, and most people do not know about it, it should be less likely that your file will change in size.

Update:
Note: "chattr +/-i file" will only work as root.

    Unfortunately now they know about it.

      pretty sure it is not a person who is doing this... so not very concerned about the -i option... wait and watch

      Note that a root user can still do whatever he wants with the file.

        As long as he executes 
        chattr -i file
        first. Without this even root can not modify/delete the file.
        I like to protect important files with the immutable flag. As such an accidental deletion/modification is very unlikely, since even rm -rf as root won't work on a file with an immutable flag set.
