Only easier in some cases; impossible in others.

$ man chattr

	chattr changes the  file  attributes  on  a  Linux  second

i.e. It doesn't work on all filesystems, which is why I'd hestitate
to recommend it. For the general case, I tend to recommend things
that work for most systems; especially the ones that I tend to use.
