Why I did it
When disk become read-only (kernel bug), it blocks new remote users access.
This fix would enable remote user access even in read-only state
How I did it
Keep monitoring disk state.
If it becomes read-only, mount /etc & home dir in tmpfs to become RW and periodically write error logs
With /etc & /home set in RW state, this allows remote user access
How to verify it
sudo bash -c "echo u > /proc/sysrq-trigger")Which release branch to backport (provide reason below if selected)
