Please disregard last paragraph in my comment #1. I've found that I was not able to boot with recurse=1 not due of read-only /var, but due of script's attempt to remount absent cdrom for which I have an entry in my /etc/fstab (added by system installer).
Nevertheless, I found new configuration useful to exclude some filesystems from recurse. For example, to properly boot with (separate) read-only /,/boot,/var and read-write /home I use string like below in my /etc/overlayroot.local.conf: overlayroot="tmpfs:swap=1,debug=1,driver=overlay,recurse=not:cdrom|home". I checked - this syntax also works for kernel command line, I only had to put recurse option in single quotes like: "... overlayroot=tmpfs:swap=1,recurse='not:cdrom|home'". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758389 Title: List of partitions for overlayroot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-initramfs-tools/+bug/1758389/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
