Still curious how they would work on, say, /var/mysql or /var/postgresql,
but I can play with this on my own.
Has anyone already tried? Care to comment?
FWIW I run softdep on ALL partitions except / and /var and have for
many years. I exclude /var because on a crash I want the best chance

If your app makes assumptions about write ordering, softdeps can negate

I had always assumed the use of softupdates was safe as long
as you could have reasonable assurances that the machine would

I've just stumbled across the SoftUpdates section in the FAQ, and was rather

help.
Even if you do mount a special partition for the logs only of httpd and
mount it softdep? On a busy site the logs are growing pretty fast at
times and can hold back some processing no?

Unless you can have two different mount point to the same partition?
Never tried it and always assume it wouldn't be possible anyway.
Then do not guess, but just try it!
