Hi,
I'd like to be able to utter cmdlines such as
$ zfs set readonly=on .
$ zfs snapshot [EMAIL PROTECTED]
with '.' interpreted to mean the dataset corresponding to
the current working directory.
This would shorten what I find to be a very common operaration -
that of discovering your current (working directory) dataset
and performing some operation on it. I usally do this
with df and some cut and paste:
([EMAIL PROTECTED]:fx-review/fmaxvm-review2/usr/src/uts )-> df -h .
Filesystem size used avail capacity Mounted on
tank/scratch/gavinm/fx-review/fmaxvm-review2
1.0T 15G 287G 5%
/tank/scratch/gavinm/fx-review/fmaxvm-review2
([EMAIL PROTECTED]:fx-review/fmaxvm-review2/usr/src/uts )-> zfs set readonly=on
tank/scratch/gavinm/fx-review/fmaxvm-review2
I know I could script this, but I'm thing of general ease-of-use.
The failure semantics where . is not a zfs filesystem are clear;
perhaps one concern would be that it would be all to easy to
target the wrong dataset with something like 'zfs destroy .' - I'd
be happy to restrict the usage to non-destructive operations only.
Cheers
Gavin
