# Breaking change
## v2019.2.1
* The ramdisk works with multiple different users
* Migration
* `sudo p3x-ramdisk stop`
* Install the latest version
* `sudo p3x-ramdisk install $USER`
* `sudo p3x-ramdisk start $USER`
* What actually changed, is that every command has a parameter `<uid>` eg.
* `sudo p3x-ramdisk install $USER`
* `sudo p3x-ramdisk start $USER`
* `sudo p3x-ramdisk stop $USER`
* `sudo p3x-ramdisk link $USER`
* `sudo p3x-ramdisk load $USER`
* `sudo p3x-ramdisk save $USER`
* `sudo p3x-ramdisk status $USER`
* `sudo p3x-ramdisk watch $USER`
## v1.1
This is only important if you have an older version (1.0.x-y) and/or you use linked folders (like IntelliJ).
It will never change anymore, but sometimes I can delete accidentally my data from the ramdisk, so I refactored the name instead of:
```text
/home/user/ramdisk/persistence
```
now it is called
```text
/home/user/ramdisk/.p3x-ramdisk-persistence
```
(hidden by default)
and if you accidentally deleted, it will be auto-recreate
(this is always visible - a symlink)
```text
/home/user/ramdisk/p3x-persistence
```
If you are linked to IntelliJ for example, you have to recreate the symlink in your home.
For example, migration looks like this:
```bash
# exit intellij if you have linked
sudo p3x-ramdisk stop
rm -rf ~/ramdisk/persistence
sudo npm i -g p3x-ramdisk
sudo p3x-ramdisk install $USER
sudo p3x-ramdisk start
# so you are already linked into p3x-ramdisk, here
# (if you are not linked, do not delete and
# do not execute below, only if the intellij
# data is linked and you are sure it is a
# symlink )
ll ~/.IntelliJIdea2018.1
```
Shows:
```text
lrwxrwxrwx 1 patrikx3 patrikx3 94 Apr 14 19:34 /home/patrikx3/.IntelliJIdea2018.1 -> /home/patrikx3/ramdisk/.p3x-ramdisk-persistence/content/.p3x-ramdisk-link/.IntelliJIdea2018.1/
```
**MAKE SURE YOU EXIT FROM INTELLIJ.**
If you are sure it is a link, you can recreate like:
```bash
rm ~/.IntelliJIdea2018.1
ln -s ~/ramdisk/.p3x-ramdisk-persistence/content/.p3x-ramdisk-link/.IntelliJIdea2018.1/ ~
```
Now you are safe.
