@Luksus In my case nothing happened as the partition was already 786432 blocks long, so that did not help.
What I am more wondering about is why is the partition table created exactly like it is? It's clearly made by Ubuntu Installer and not Android (when Android [e.g. LineageOS] is installed, the partition table is definitely different.) And the partitions are crazy (see below)
So I hypothesise that it's possible to change the partition table setup [e.g. create root at /dev/sdaX, see below] at installation time, but not sure yet how -- any ideas?
Also, I see that /dev/sde is 4GB. I wonder if this is on the hardware level, or there is another mapping level done by linux kernel -- will check this again by reinstalling Android and looking at the devices. journalctl or dmesg don't hint whether or not these are separate devices; however, udev shows each of them has its own SCSI LUN which I think implies these are indeed separate devices.
P.S.
/dev/sda: 113.6G (out of those, 113.2G mounted at /userdata)
/dev/sdb: 4M
/dev/sdc: 4M
/dev/sdd: 128M
/dev/sde: 4G
/dev/sdf: 1.5 (1G mounted at /var/lib/lxc/android/rootfs/vendor)
