New Revision: 219578
URL: http://svn.freebsd.org/changeset/base/219578
Log:
Use the allexport option in load_rc_config() in order to avoid having
to repeatedly read the conf files. Depending on what is enabled the
files are being read anywhere from 15, 30, or more times currently.
By loading the values in the environment this is reduced to 1, with
perhaps a couple more, again depending on what is enabled.
I wonder if it is a good idea to pollute the environment of many daemons
with this. Although sshd and cron clean it up, there is at least one
daemon that passes the environment on. One of those is devd. While that
saves four /etc/rc.conf reads on my minimalistic 9-current VM, it
implies that devd must be restarted to pick up changes to /etc/rc.conf.
That seems a POLA violation.
devd shouldn't be passing this to its children. imho, devd should be
fixed to be more robust.
