The output without the dollar sign is less confusing as it's actual
valid shell syntax:
$ /etc/rc.d/foo rcvar
# food
food=YES
Brought up on tech-userlevel@ by Rocky Hotas with some LGTMs from
other people and no objections.
We still refer to '$food' in warnings/errors though.
The /dev/acpi character device gives an aperture into physical memory
that allows only read access to known ACPI tables: RSDP, XSDT/RSDT, and
the root tables. Adapt acpidump(8) to use this interface by default,
falling back to the old /dev/mem method if it is not available or if
ACPIDUMP_USE_DEVMEM=1 is set in the environment. The user visible benefit
of this change is that "options INSECURE" is no longer required to
dump ACPI tables.
- Use "-6" instead of "--noipv4" as it seems more appropriate based on
the dhcpcd(8) manual page.
- Remove "-f /dev/null" as it seems unnecessary with "-6".
- Remove "--persistent" as it is in the default /etc/dhcpcd.conf,
and this way the user can change it, if they would like to (either
through dhcpcd_flags or by editing /etc/dhcpcd.conf).
The "-b" (or "--background") option is needed to avoid a timeout error
message (and a delay in booting), so it is still left in place.
- Use the "pool" keyword for obtaining servers from ntp.pool.org.
- Add "tos minclock" and "tos maxclock" to limit the number of servers.
- Add "restrict source" to apply appropriate restrictions to servers.
(Specifically "nopeer" cannot be applied to "pool" servers.)
- A single "pool" entry suffices -- using "2.netbsd.pool.ntp.org" so
that we get both IPv4 and IPv6 addresses. (No addresses are returned
for just "netbsd.pool.ntp.org.")
- Add a comment about "tinker panic 0" -- useful for VMs and laptops.
- Add a comment about "discard minimum" -- useful for some SNTP clients.
- Add an explanation for the "limited" restriction keyword.
- Unify whitespace and comment formatting.
This results in correct updates to /etc/motd even when the value of
motd_release_tag is changed (a likely event).
Add safe quoting to outputting the read kernel version.
Thanks to kre@ for the feedback.
My personal preferencese for /etc/rc.conf:
update_motd_release=YES
motd_release_tag='Binaries: '
This provides an explanation to users about the second version in motd.
builds on modern systems and seems to have been added as a workaround for
some 2004-era Linux NFS bug. Guessing that the issue has been sorted out
in the meantime.
Still planning to replace wgconfig(8) and wg-keygen(8) by one wg(8)
tool compatible with wireguard-tools; update wg(4) for the minor
changes from the 2018-06-30 spec to the 2020-06-01 spec; &c. This just
clarifies the current state of affairs as it exists in the development
tree for now.
Mark the man page EXPERIMENTAL for extra clarity.
