This is very interesting to me, as I are currently working on a jail
design and nullfs has a number of question marks next to it, mainly
due
to the scary man page warning. Here are a few of the questions:
How did you decide it was trustworthy?
I did a few tests and read some archived posts from others using it.
I was previously using a localhost nfs mount but wanted to eliminate
nfs from the mix due to another issue I was having.
Does it result in lower RAM usage? (The program that is run, for
example, Apache, comes from the same spot on the disk across all
jails.)
Don't know. Never did any tests.
Is it currently maintained? The man page includes a maintainer
solicitation.
Don't know. However, archived posts lead me to believe that bugs
have been fixed etc recently and the man page may be out of date.
Have you had any problems in production?
Not that I know of. Seems to be running fine with over 40 jails on
the machine. Most are READ ONLY but I do have one jail with a RW /
usr so it can install ports etc. I have a /usr/public I install
ports into for all jails to use.
Have you used it for long?
A few months. Previously I was happily doing the same thing with the
localhost nfs mount.
best
