Without knowing anything about the underlying structure of a working
copy, I would actually agree with original poster that a) this is a
desirable behavior (feature) and b) this somehow feels like an
"expected" feature in an SVN client.
As someone who switches between operating systems routinely, I would
hope and expect that my working copies are usable from within either OS,
and with any SVN client. Like the OP, I have done this in the past, and
without issue (to my knowledge).
That said, my experience has been that the SVN developers don't
undertake an action unless the rationale is sound (or well-intentioned,
at the least). So, I'm sure there is a good reason that we shouldn't
expect this capability.
Would anyone with the technical background to comment be willing to walk
us through why cross-OS working copies are not possible and should not
I'm not trying to sound ungrateful; I just need to set expectations
reasonably (for myself, and for those who depend on my advice).
