Hmm, but why make it executable at all if it's a text file?

In nay case, it's not going to do anything at all to prevent the file from
being deleted, delet/rename priv's are dictated by the write access of the
directory the file is in, the permissions of the file itself have no
effect on that....

the extended attributes are a special exception to that, making the file
immutable essentially tells the kernel to ignore the directory and refuse
to modify the files's inode properties....including it's entry in the
directory that contains it

chattr can be a bit of a surprise if you forget you used it tho, i tend to
recommend some caution here ;P
