Comment 61 for bug 1650688

Test result on Focal (245.4-4ubuntu3.14):
- Normal environment: Tested on my desktop. timedatectl output is correct. Setting the timezone works, and doesn't put the link inside /etc/writable/.
- System-image environment (UBports image): timedatectl output is correct. Setting timezone works; readlink -f /etc/localtime points to an existing file.
- Ubuntu Core environment: test with snapcore/core20 commit 2d970050. focal-proposed is enabled and src:systemd is pinned in overlay. timedatectl output is correct. Setting timezone works; readlink -f /etc/localtime points to an existing file.

Test result on Bionic (237-3ubuntu10.53):
- Normal environment: Tested in an LXD container. timedatectl output is correct. Setting the timezone works, and doesn't put the link inside /etc/writable/.
- Ubuntu Core environment: test with snapcore/core18 commit b8ad5ed4. bionic-proposed is enabled and src:systemd is pinned in overlay. timedatectl output is correct. Setting timezone works; readlink -f /etc/localtime points to an existing file.
- System-image enviroment: We at UBports doesn't have a port of Ubuntu Touch based on Bionic, and as such I cannot test in this environment.

Note: in Ubuntu Core environments, timedatectl.real is used to test timedated instead of the wrapper.

Note: according to [1], seems like verification-needed* has to be left as-is until another positive testimony appears or the test is done by an SRU verification team member.

Oh, BTW, I looked at the autopkgtests failure earlier. One of the failure (can't remember which) was because of an out-of-space error. It seems to be gone by now though.
