Yup - I would only use it if you really are doing a copy and not a |
7 |
move (neglecting the fact that the implementation of a |
8 |
cross-filesystem move does a copy first). I imagine many ebuilds do |
9 |
copy operations internally, but probably not to an extent where it |
10 |
would make much difference. I'm not sure how doins/dobin/etc are |
11 |
implemented - I think they're copies and so allowing for the fact that |
12 |
not everybody uses a tmpfs it might make sense to fix those. |
