More of a problem than chmod the more typical problem I see is when
users copy files through a USB storage device on a FAT32 or NTFS
filesystem.  Since those don't have Unix file system permissions
then using them to copy files results in files being mode 777.  And
then almost no one seems to fix them subsequently.  Sigh.
