Every now and then service fails to start when computer boots up. I have started noticing it around this month only.
Roughly 1 in 5-10 boots, without any apparent pattern.

Can confirm this bug on Ubuntu 20.04.3 LTS. The log seem to be the same as above.
Someone on discord commented that this may be related to swap not being properly stopped on shutdow. I am not sure.
Maybe it has something to do with poor timing during boot since the issue is appearing at random?
I just restart a bunch of times to see if it failed, and it failed everytime. So maybe on Ubuntu 20.04.3 LTS it is a different problem?
Anyway, I make a wild guess that maybe the zram module somehow not loaded on time (?), so I added the zram module to initramfs module list, and now it seem to successfully create the swap.
Note that I have no idea what I'm doing, so please do not consider this as a solution without some (or a lot) more investigation.
I've forked this repo and found that britishbadger@3adea21 the following options seem to result in everything starting correctly from boot.
Thank you, will test ASAP.

@britishbadger it fails to start still, but the frequency is much lower now, around 1 in 10-15 boots.

So far no more, it seems.
No more failures since last report.
