Changes are copied into the memory
Posted: 19 Apr 2018, 21:03
First I want to congratulate the Porteus team for creating such a fantastic OS. With my bug reports I want only to help it to be better not to criticize the developers' work. I found a few ones, so I think I create a different bug report for all.
When saving the changes, the changes are copied into the
memory
I use Porteus LXDE 4.0rc4 64bit version. (I am glad that you made LXDE version too, wich is the fastest and most user-friendly DE ever.) The content of ISO was copied into boot/porteus/Porteus-LXDE-v4.0rc4-x86_64 directory of my internal HDD (with only 1 partition). I boot Porteus with GRUB2. The menuentries in the grub/grub.cfg file:
While using persistence, I used also Wine which created about 500M size directory in home. Then I observed that my available memory significantly decreased. The reason was that the changes directory was not loop mounted but directly copied into the RAM. If this is the normal behaviour of Porteus, this is not a bug report. But if so, I will use Porteus always in live mode. 
Boot with persistence, using boot/porteus/v4.0-rc4_c1/changes directory:
Boot in live mode:
The shared memory difference is: 70-24=46 : the size of changes directory. Meantime I deleted the big wine directory from home, but this also shows that the changes are directly copied into the RAM.

Unfortunately "/" does not help in this case.
