In FreeBSD, when you do make config, lots of ports have options that can be set. These options are saved so that when you update the port, they are used again.

Some ports have additional items that are checked for in the Makefile, but not exposed as a configure option. For example, the maildrop port has the MAILDROP_TRUSTED_USERS checked with the following if statement in the Makefile:

.if defined(MAILDROP_TRUSTED_USERS)
   CONFIGURE_ARGS+=        --enable-trusted-users="${MAILDROP_TRUSTED_USERS}"
.endif

I'm having a brain fart, where can I set MAILDROP_TRUSTED_USERS so that it will be used if the port get updated later by postmaster? For this install I defined it manually, but if I use postmaster to update a port that forces this port to update, I'd like the value be set for the build.

I'm running a Linux system that starts a custom text mode application from the .bashrc. The users are getting disconnected due to network dropouts.

I had the idea that I'd use screen to allow them to get back to the prior session, but I like to make sure that they can't open a subshell that allows access to the UNIX command line (or for that matter, another login).

I've modified .screenrc with the following: bind c bind ^c

To prevent the Control-A Control-C command from working. Are are any other security issues that I need to be a where of here?

I have a FreeBSD system with a 750GB boot drive (UFS boot, ZFS root) and a second data made from a three drive raidz setup. I'd like to swap the three 250GB drives for a trio of 2TB drives. Assuming that I have enough room on the root drive to make a copy of all the date from the raidz setup, what would be the simplest way to swap out the drives?

Should I just copy out all of the data, destroy the pool, power down the system and install the drives and then boot and recreate the pool and then the file systems. Then restore the data back to where it was?

Is there something that I can do that would be less work?

This is on a 1U rack mount running FreeBSD 7.2 (Built from sources on 20090920).
