The shell cannot handle 64-bit inode numbers inside the .checkpoint directory when uniqueino is enabled

Due to a limitation with the AIX operating system, the shell cannot handle the 64-bit inode numbers inside the .checkpoint directory when the uniqueino mount option is enabled. Some shell functions such as auto-complete and globs, for example rm *, do not function properly in the .checkpoint directory. This also affects 32-bit applications that try to read the contents of the .checkpoint directory or any of its subdirectories. This does not affect any 64-bit applications.
