Hi, on my tablet PC I used an Android App called "Linux deploy" to install an chroot-environment for - guess - Gentoo. :)
The tablet has a SDcard slot and recognizes any FAT32 formatted SDcard automatically. Anything else will silently be ignored. Furthermore Linux deploy uses a single file when it is pointed to an external SDcard (with FAT32) which is mounted via a loop device, formatted ext4, and then populated with the Gentoo Linux files. So far so nice. Unfortunately the file size is limited to 4GB, which is not /that/ much in respect to what I want to install later (Linux deploy goes as far as LXDE runs a terminal and only a few moe things). I created a second file of 4GB and set it up as a "second partition". This is now additional storage capacity of another 4GB. BUT: Linux deploy already installed a full rootfs and more on the first file. And I need to increase the size of _the whole rootfs_ with this extra file ... not only the storage capacity located behind a certain mountpoint. Is there any way to add the capacity of the second file in a way, that the whole rootfs participates from/in/at/of (damn! sorry, I am not good with/at/in/of/from propositions) this? How can I deal with this? Thank you very much in advance for any help! Best regards, Meino
