suppress ensureLink & ensureSymlink dest exists error

[reggi]

Here's the dest error suppressing for ensureLink thoughts? I'd do the same for ensureSymlink

Added symlink in here too, and rebased to one commit.

Thanks!

Hmm... what if the link exists but it's to another source?

@jprichardson This doesn't check the type of the file, or if the content is the right content. The way I understood ensure is, "ensure it's on the system" if it exist's in any way shape or form it's ensured, no? This could check if it's ensured as a specific type of path (using stat) and if the content is what it should be. But then what? Throw an error? I'm pretty comfortable with this as it is. I do want to see the extensible range of ensure derivative functions that I talk about here I'd chalk all this functionality into a ensureMatch derivative.

tl;dr I'm ok with if it's to another source, it's ensured to exist

Fair points. We'll leave it as is for now.
