Should not, but for some values of "sometimes" it makes sense, eg. capturing image of an otherwise quiescent filesystem, a read-only mount or after a crash. This utility is used for debugging so I'd prefer to let the user do as he likes, though printing the warning about the mount status is a good improvement. > The undergoing fs operations may change what you have imaged a while ago, > this makes the image meanmingless. I'm not familiar with the image format, but maybe we can set a bit in the header when the filesystem was not captured cleanly. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
