If you want to try out revert functionality - you can do it in a next way:
After you created all the stuff, print history like this:
`solar ch history`
Output:
```
log task=hosts_file1.run uid=282fe919-6059-4100-affc-56a2b3992d9d
log task=hosts_file2.run uid=774f5a49-00f1-4bae-8a77-90d1b2d54164
log task=node1.run uid=2559f22c-5aa9-4c05-91c6-b70884190a56
log task=node2.run uid=18f06abe-3e8d-4356-b172-128e1dded0e6
```
Now you can try to revert creation of hosts_file1
```
solar ch revert 282fe919-6059-4100-affc-56a2b3992d9d
solar ch stage
log task=hosts_file1.remove uid=1fe456c1-a847-4902-88bf-b7f2c5687d40
solar ch process
solar or run-once last
watch -n 1 solar or report last
```
For now this file will be simply cleaned (more cophisticated task can be added later).
And you can create revert of your revert, which will lead to created hosts_file1
resource and /etc/hosts with appropriate content
```
solar ch revert 282fe919-6059-4100-affc-56a2b3992d9d
solar ch stage
log task=hosts_file1.remove uid=1fe456c1-a847-4902-88bf-b7f2c5687d40
solar ch process
solar changes run-once last
watch -n 1 solar changes report last
```
After this you can revert your result of your previous revert, which will
create this file with relevant content.
```
solar ch history -n 1
log task=hosts_file1.remove uid=1fe456c1-a847-4902-88bf-b7f2c5687d40
solar ch revert 1fe456c1-a847-4902-88bf-b7f2c5687d40
solar ch stage
log task=hosts_file1.run uid=493326b2-989f-4b94-a22c-0bbd0fc5e755
solar ch process
solar changes run-once last
watch -n 1 solar changes report last
```
