I checked the folder that takes most memories using Space Inspector, and I saw that the folder /home is duplicated into /opt/alien. I confirmed it using File Browser. It is annoying as the home takes most of the used memories, thus it takes twice more memory than I should.

Your home is mounted into /opt/alien/home. You may check with findmnt -R /opt/alien/home. It is a bind mount (mount -o bind DIR1 DIR2) which is in short a hard link for directories.
Symlink is not appropriate in this case as symlink can not penetrate chrooted environment.

Have you checked if it is a hardlink? I think this can't be shown by file browser. you have to check it in terminal. Look for same node with
ls -i
Indeed it seems it is a hard link. I'm not familiar with this kind of link, but it appears that it still takes twice the memory (or at least the system think that it takes twice the memory, what would be problematic).
Wouldn't it be better to use a symlink instead?

As you can see, it just thinks it takes up space, symlinks tell how big the link file is, hard links tell the size of the linked files. At least that's how I understand it.
Anyways, it is a problem that Sailfish count the memory twice, and I suspect that there will be some problems when it will think it is full (even though half the total memory is free), such as impossibility to update the system (I remark this problem because Sailfish told me that it remained not a lot of memory).
For information, I never had this problem before the last regular update (1.1.2.16).
Vivien ( 2015-05-02 19:29:11 +0300 )Don't worry, Sailfish does not count the memory twice, you should go read about bind mounts.
If you have memory issues, it's because of that: https://together.jolla.com/question/30822/root-and-home-disks-full-and-causing-various-problems/
Sthocs ( 2015-05-02 20:39:21 +0300 )Yes you are right, the memory in not counted twice. Thank you everyone to show me why it is not a bug. I'll close the task.

I can confirm this. If it is needed in /opt/alien it should be a symlink.

coderus ( 2015-05-02 20:09:25 +0300 )Ah. I should have tried to run
