Disabling journaling for read-only ext4 fs
Question
If journaling is disabled for a read-only ext4 fs can there be any possible side effects?
I see an opportunity of saving precious storage quota by doing so.

The answer is Yes as per https://wiki.debian.org/ReadonlyRoot#Preconditions
You can use a filesystem without a journal for /, because you don't write there and you don't need the journal.
