Re: [zfs-discuss] Can ZFS be event-driven or not?
Hmm, two thoughts on this: 1. For anyone interested, didn't VMS do something like this? Perhaps a look at its design and implementation would be useful here. 2. For the per-application issue, there are ways to handle that. First, make a ZFS api for providing file-level snapshots. Then, a library wrapper around the normal syscalls (open,close,read,write,etc) that invokes the zfs apis as needed. Either the wrapper is smart enough to know which app wants which behavior (perhaps even specializing also on the path of the file), or several libraries available for different tasks. Shove it/them in something like LD_PRELOAD and you'd be good to go. As for utility, I think this sort of thing would be fantastic in certain areas. If you can develop the feature set cheap enough, then it's a real win. I haven't touched ZFS's internals (in code or even dev docs), so I don't know what kind of work's required to pull off file-level snapshots. -- H.

I think Apple's waiting until ZFS's got a few more things ironed out. The big concerns seem to be massive bulk I/O for video, maybe more reliability/testing on their part. -- H.

Re: [zfs-discuss] ZFS Crypto Alpha Release
A few things come to mind: * Attaching a label to the zfs filesystem, so I can't mount the FS in an unlabeled or differently-labeled zone if I don't want to. (multiple labels for shared fs's would be cool, too.) * Connecting the startup of the trusted zone (I'm still learning this stuff, sorry if I'm completely off) to the mounting of the filesystem -- I guess these two are similar, in enforcing access to the restricted data to the restricted environment. Perhaps requiring the keys to the fs's as the zone boots. * Straightforward setup to set them both up together. On a portable or an easy-to-steal desktop, the trusted zone's don't help me much without an encrypted store for it. Encrypted ZFS is useful by itself, but trusted zones with a disk that can get stolen needs encryption. Optimally, that mind-boggling 2-line setup procedure for my ZFS setup would be the model for setting up both a zfs encrypted store & a trusted zone atop of it.

Re: [zfs-discuss] ZFS Crypto Alpha Release
Looks great.. Any (long-term distant-future) plans of integrating this with the Trusted Extensions for a real quick setup? With a check to make sure the key's password != the label, just to be sure :-P This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
