While I tried again to install 16.04 on pre-formatted LUKS + lvm2,
- I created an USB(3) live stick (with usb-creator-gtk, from 14.04).
- There I choosed a permanence of 4 GiB, for preserving my work and tools for the coming installations.
But now I see on the mounted stick a folder "casper" with a size of about 1,5 GiB, which is about the size of the 16.04 image.
Now the experience of my last try tells me that, on the live system
The root file system "/" was on the device "cow", with the size of 1,5 GiB, 500 MiB left, which were uses up in the middle of the first step of the installation, forcing me to break up.
- [although: I see there the file /media//B6A3-7DB8/casper/filesystem.size, containing the number 4186521600 (bytes?) What is that for?]
(Referring to usb-creator-gtk) I think that:
- The persistence sizing up to 4 GiB does not do its job.
- The persistency is not made for data of substantial size (while it it may work, say for a couple of conf files).
Are my above statements right?
