Hi all,

I have just installed the Ubuntu touch 20.04 on my OnePlus 5T, and realised that the root partition was created very small:

phablet@ubuntu-phablet:~$ df -h
Filesystem                          Size  Used Avail Use% Mounted on
udev                                3.7G  744K  3.7G   1% /dev
tmpfs                               769M  4.8M  765M   1% /run
/dev/sda13                          111G  2.6G  103G   3% /userdata
/dev/sde21                          2.9G  2.7G  190M  94% /
/dev/loop0                          457M  295M  153M  66% /android
[...]

I have found some instructions to resize the partition, however they seem to be targeted at situations where / is mounted over the loop from a file in /userdata (e.g. system.img). However, on my phone this does not seem to be the case: the only loop device mounted in a 457MB partition mounted at /android; the actual root is on /dev/sde21 (see above), and the partition table on /dev/sde is wild! Also I am curious where the 6 storage devices come from (sda..sdf), but that's another story.

So the question is: is it possible to (a) read some info somewhere on why so many partitions are created during the installation, and (b) during the partitioning stage alter the size of the root partition? I was using ubports-installer on Mac OS, and it obviously didn't give those options.

Thank you!
