You can do all of this except the "subdirectory snapshots" today. You
can use a different delimiter (eg. '-') to accomplish much the same
thing. We'll consider adding the subdirectory snapshots, which could
potentially make managing a large number of snapshot easier.
For example, today you can do:
# zfs snapshot data/[EMAIL PROTECTED]
# find .zfs/snapshot -name "daily-*" -ctime +7d
# rmdir `find .zfs/snapshot -name "daily-*" -ctime +7d`
# mv .zfs/snapshot/today .zfs/snapshot/daily-2006-05-10
The 'rmdir' effectively does a 'zfs destroy', and the 'mv' effectively
does a 'zfs rename'.
