Good day.
After analyzing my conversation with Doug Barton about 'return' vs
'exit' in the rc.d script I had found the weak point in my arguments:
when rc_fast_and_loose is set, rc.d scripts are directly sourced
into the /etc/rc, so any call to 'exit' will interrupt /etc/rc
in this case. The function err() from rc.subr does call 'exit'
and for -CURRENT I see at least 13 scripts that use err() to signify
run-time or configuration errors:
{{{
$ grep -r 'err[[:space:]]*[0-9]' . | cut -f 1 -d : | uniq
./bluetooth
./ipfilter
./ipfs
./jail
./mdconfig
./mdconfig2
./named
./nfsd
./ipmon
./routing
./netif
./accounting
./netwait
}}}
power_profile and dhclient were pruned from the list, because they
err() only on the bad usage.Looks like that rc_fast_and_loose isn't used much, because otherwise some machines will go single-user on a certain failures of the above scripts. CURRENTly, no things in /etc use or set rc_fast_and_loose, apart from the /etc/rc.subr itself: it only checks its value inside run_rc_script. rc_fast_and_loose was introduced in http://svnweb.freebsd.org/base/head/etc/rc.subr?revision=98186&view=markup {{{ Revision 98186 Thu Jun 13 22:19:42 2002 UTC (9 years, 6 months ago) by gordon File size: 23163 byte(s) Bring this up to date with the latest NetBSD bits. Also add some bits of our own. Submitted by: Mike Makonnen Reviewed by: silence on -current and -hackers }}} but I can't extract any useful bits regarding the need of rc_fast_and_loose from this. So, the question is: what is it good for and how people use it?
