x86: Running the ludelete Command Can Delete

Shared Datasets Not Related To the OS (15817477)

Running the ludelete command can delete shared datasets that are not related to the OS in the

following scenario.

Consider that a boot environment BE2 is created from BE1. After booting into BE2, you create a

dataset dm2, and also create a boot environment BE3. Subsequently, if you change your boot

environment to BE1 and choose to delete BE2, the dataset dm2 is also deleted.

The following example explains the scenario.

Consider that you have an active boot environment BE1 with an existing poolname that has

various datasets containing data not related to the OS.

1. Create a boot environment BE2.

lucreate BE2

2. Activate BE2 and reboot.

luactivate BE2; init 6

3. Create a new zfs dataset dm2 under the existing poolname.

4. Create a new boot environment BE3.

lucreate BE3

5. Activate BE1 and reboot.

luactivate BE1; init 6

The active boot environment is now BE1.
