Comment # 13

from Marcus Schaefer
I've setup an integration test based on your MicroOS description such that we
have continuous testing of the feature set needed here. This image can be found
here:
https://build.opensuse.org/package/show/Virtualization:Appliances:Images:Testing_x86/test-image-MicroOS
Based on that build I run a VM, and it comes up with the following layout:
---

>From a partition perspective it looks like this
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
fd0 2:0 1 4K 0 disk
sda 8:0 0 24G 0 disk
������sda1 8:1 0 2M 0 part
������sda2 8:2 0 20M 0 part /boot/efi
������sda3 8:3 0 19G 0 part /
������sda4 8:4 0 5G 0 part /var
sr0 11:0 1 1024M 0 rom
So /var is at the end and growable
If you are looking for code that could grow the partition. I wrote this code
for the public cloud. It is designed to grow root but it can easily be adapted
to just grow whatever is last
https://github.com/SUSE-Enceladus/rootgrow/pulls
Does this provide the desired layout ?
One question from my side. The system is read-only on /etc and other parts of
the rootfs. I guess this is by intention ?
Thanks
