the wheel group has no explicit members listed in /etc/group. This adds
the "exempt_if_empty" flag to pam_wheel in the default configuration;
in some environments, it may be appropriate to remove this flag, however,
this default is the same as pre-pam_wheel.

to help clean up. After selecting a potential buffer to write, this
patch has it acquire a lock on the vnode that owns the buffer before
trying to write it. The vnode lock is necessary to avoid a race with
some other process holding the vnode locked and trying to flush its
dirty buffers. In particular, if the vnode in question is a snapshot
file, then the race can lead to a deadlock. To avoid slowing down the
buf_daemon, it does a non-blocking lock request when trying to lock
the vnode. If it fails to get the lock it skips over the buffer and
continues down its queue looking for buffers to flush.

NB: Open_Disk should redo how it malloc's memory so the caller can free

reclaim everything but this leaks the indirect strings. Fixing this

2. Update a comment. We now restore much more than RTC updates and
interrupts.
3. Order change. Stop interrupts by writing to RTC_STATUSB,
restore rate bits for the interrupts by writing to RTC_STATUSA,
then enable interrupts again.
This seems to be done perfectly backwards in startrtclock().
Otherwise, the idea for this change was obtained from

Fixed the value of SC_CUT_SEPCHARS. Setting this value would have had no
effect even if it were used, since the value was the same as the default.
The above bugs had no effect except to set bad examples, since test
coverage of SC_CUT_SEPCHARS is broken by enabling a negative option.
Removed (unquoted) double quotes for all options. They were all bogus
since they had no effect except to make non-strings look like strings.
Most of the non-strings were expressions. The value of INIT_PATH is
a non-string since it is stringified later (unlike SC_CUT_SEPCHARS).
Fixed parenthesization errors inside bogus quotes (parenthesize values
if they have more than one token in them but don't parenthesize single
tokens).
