| Because vnds are specifically configured for mounts; the only thing
| they're useful for is mounting a fs image that lives in a regular
| file.
No they're not, they can be used for playing with newfs variants,
fsdb, fsck, resize_ffs, ... Nothing requires they be mounted.
| It looks like we (still) don't have the ability to implicitly (or even
| explicitly) configure a vnd when you try to mount a file, which Linux
| has had for a long time. But we should really get that sometime.
Perhaps, but that's an unrelated issue. And I suppose it should automatically
configure a cgd when you try to mount an encrypted file?
| It's really fundamentally different from things like raids that have
| independent existence.
I disagree, the only purpose of a raid is to provide filesystems (and perhaps
swap) which can be mounted - the only purpose of ccd is ... (and s/ccd/cgd/)
All these things model hardware devices in software, adding their own local
peculiarities (running in a file, redundancy, encryption, ...) but all of
them, vnd included, are more or less the same basic thing.
