Hello, Everyone!

I'm trying to change www/payara port to make it run under the payara
user instead of root.
I've added the following line to the UIDs file:

payara:*:221:221::0:0:Payara Application Server
user:/nonexistent:/usr/sbin/nologin

And this line to the port makefile:

USERS=        payara

Also, I've made some another changes to the port's scripts to start
service under payara user.
Everything seems to be fine, but the service on start/shutdown creates
some preferences files,
caches, etc in the payara user's homedir.
The problem is, that it is impossible to create these files in
/nonexistent. This fact makes
service to show some annoying warnings on every startup/shutdown.
To make service to work properly I want to create directory writable by
the payara user and
set it as payara's homedir.
And I don't want to put these dir under the /usr/home/, it should be
somewhere in the application,
like /usr/local/payara-4.1.2.173/prefs.
As far as I understand, payara user will be created automatically by the
bsd.port.pre.mk file included in the port's makefile. But, during every
installation somehow payara user's homedir
should be changed. I can do it with the following one-liner:

/usr/sbin/pw usermod payara -d ${DATADIR}/prefs

So, the questions are:
1. Is it a proper way of doing such kind of things?
2. Where in the port's makefile should I put my one-liner? Will it be OK
to make it like this:

.......head of the make file with setting variables and so on is here......
.include <bsd.port.pre.mk>
do-install:
     .........doing some work here......
     @/usr/sbin/pw usermod payara -d ${DATADIR}/prefs
.include <bsd.port.post.mk>
....end of the makefile.....

Many thanks for your attention and help.

I don't know Payara but applications should not write its files to /usr/local. This should work even if /usr/local is mounted Read Only. If you need to store configuration (preferences) then it should be in /usr/local/etc/payara. If the application writes some data files like databases, it goes under /var/db/payara and log in to /var/log/payara.log or /var/log/payara (directory)
