Simply things so that "#REQUIRE: FILESYSTEMS" means the file systems are fully "ready to go". 'FILESYSTEMS' states: "This is a dummy dependency, for services which require file systems to be mounted before starting." However, we have 'var' which is was run after 'FILESYSTEMS' and can mount /var if it already isn't mounted. Furthermore, several scripts cannot use /var until 'cleanvar' has done its thing. Thus "FILESYSTEMS" hasn't really meant all critical file systems are fully usable. 2012-09-11 07:04:59 +02:00			`# REQUIRE: FILESYSTEMS hostname sysctl FILESYSTEMS ipfilter`

Prepare for the removal of set_rcvar() by changing the rcvar= assignments to the literal values it would have returned. The concept of set_rcvar() was nice in theory, but the forks it creates are a drag on the startup process, which is especially noticeable on slower systems, such as embedded ones. During the discussion on freebsd-rc@ a preference was expressed for using ${name}_enable instead of the literal values. However the code portability concept doesn't really apply since there are so many other places where the literal name has to be searched for and replaced. Also, using the literal value is also a tiny bit faster than dereferencing the variables, and every little bit helps. 2012-01-14 03:18:41 +01:00			`rcvar="ipmon_enable"`
Use ${name} in pathnames where appropriate. The sendmail script already was on this way, but it didn't reach the end of it yet. 2005-10-28 18:55:38 +02:00			`command="/sbin/${name}"`
Luke Mewburn has indicated that they (NetBSD) are not interested in keeping the scripts under rc.d in sync with us. So, remove NetBSD specific stuff (which made our scripts more complicated than necessary). The NetBSD ident string will be left intact, both for history and also incase we wish to pull in future versions. 2004-01-17 11:40:45 +01:00			`start_precmd="ipmon_precmd"`

Allow starting /etc/rc.d/ipmon if ipnat is enabled but ipfilter is not (in /etc/rc.conf). This fixes an apparent confusion between test(1) and sh(1) syntax for AND/OR.
