The softdep flag is cleared when you change a mount to read only. What
would a read only softdep filesystem do?
Well, obviously not much regarding softdep, but I can understand the
concern.
I do the 'mount -uw / do_stuff / mount -ur' dance as part of my backup
system in order to minimize fsck time and disk corruption in case of
unexpected power outages etc. I don't have softdep on those, but that's
not really the point.
I can see situations where having to unmount and remount of a filesystem
would be a nuisance. Are there any known problems with preserving the
softdep bits (and even allow, albeit at that time ignore, them if
present at 'mount -r')?
