[BUGS] NFS root and GJournal

[Peter Ross]

Hi all,

I am playing around with virtualisation and ZFS etc and have some  
thoughts related to booting from a small device (having a SSD e.g.)  
and using a storage server having ZFS and all that "fun staff" (BTW: I  
have done jail deployments for 4 years and simply loved it, it is what  
Dockers should be;-)

I wonder whether it is possible to run GJournal in front of it, as  
described in the handbook for UFS.

I would not worry about file locking on NFS etc. too much because the  
client has a dedicated ZFS. NFSv4 offers delegation but I have my  
doubts whether I can achieve that using the NFS boot module because I  
would need a "callback server" (nfs4cbd).

But in the situation I would not not need all that lock related magic,  
so a "NFS4lockless" would be ideal;-)

I wonder how much of this exist and is usable.

It is a bit of a play at the moment, I am just bored in my Linux job.  
It's so yesteryear;-) I frequently think about solutions with FreeBSD  
(because Linux feels clunky in many ways) but it is a no-no where I am  
working, unfortunately.

To be honest, Greg's housewarming e-mail reminded me of the list. I am  
happy to invite myself in case it happens;-)

Regards
Peter
