Hi, this is my first question. I needed to mount root (/) with read only. I've searched the openSUSE website and found how to do it. It worked fine, but my touchscreen didn't. When I changed back to "rw" in fstab (and all the files that I changed before), the touchscreen worked again. Anybody know how to fix this? There are a lot of reasons you do not want to mount root as RO. Depending on your configuration, the directories, /var and /tmp must be read-write. /var contains subdirectories for logging, spooling, and other purposes.
The /dev directory also needs to be available because there are some
dynamic devices, such as USB, CD.
Normally, root is read-only in single-user mode (run level s or 1).
Additionally, when root is read-only, you can't mount other file
systems. As Theo points out, "mounting / ro is not how the FS is meant
to be used"
