Journaling layer update - any really good programmer want to start working on the userland journal scanning utility ? You need to have a LOT of time available!

Personally I would prefer it in fstab, potentially with flags of the
sort used to keep
similar off-box backup storage 'safe', such as 'noxec', nosymfollow',
For a user who is familiar with unix or unix-like systems but new to
dflybsd, the first thing he may be trying is 'man mount' or 'man fstab'
if he wants to look for any fs-related options he doesn't know.
ACK, and of course the DFLY version of these man pages must include the
new/different features. Or 'see also.'
But I also see the point of not 'complicating' fstab - which is
historically perhaps more
The DFLY potentially-distributed/exported stored-elsewhere, etc.
journaling seems to
overlap into traditional turf of off-box logging, NFS, cpdup, rsync,
(or all of the above) in one feature or another - if only 'distance'.
The format needed to control it may not be a good fit with legacy fstab
mountctl.conf sounds relevant and neat too :)
Perhaps the best way, but again it might be more intuitive if it were:
I like the way DragonFly is going, appreciate the value of compatibility
its 'roots', but believe that the departure in core architecture easily
a more visible difference in 'sysop-land' configuration tools as well.
Many folks can be expected to be admin on other BSD, Linux, and such as
DragonFly. Forgetting which is which can bite....

I think we'd want something like an /etc/mountctl.conf, yes. I'd
it into /etc/fstab if I could, but /etc/fstab is already too full of
How about creating:
'/etc/jfstab' - or '/etc/dfjstab'
..specifically, and only, for the purpose of managing this
Keeps it out of potential confusion with non-DragonFly tools...
