What do you mean by "System" in RO mode ? You only show one particular loopback mount unit, what about all the rest ?

/srv mounts are designed to work with ZRAM so you must not expect them to work when you disable it (no need for that anyway)

Try replacing After= in /etc/systemd/system/srv*.mount by Wants=.

You are right. I've used the /srv/ mounts as a working directory. I realize that it's not working anymore to use it that way as per design together with zram. I'll close this bug. The Zram is a good alternative, in my case I have a durable sd-card and perfer to write on that instead of in RAM. I use ZRAM on other installations.

Nonetheless please Try replacing After= in /etc/systemd/system/srv*.mount by Wants= and let me know if that works with and without ZRAM running. If so we could change it for everybody.

I tried Wants= didn't make a difference. I don't know why they're in RO, but you can do systemctl restart srv-openhab2* to get them RW again.
