Hi Leo,

One more thing:

It would be better for 'new' to be simply "5.26.2" instead of an
absolute file name.  If I'm not mistaken, on ext4, files (including
symlinks) smaller than 60 bytes are stored entirely within the inode,
saving both a disk block and a seek operation when accessing it.

      Mark
