terminates the string in all cases, based on code from netstat(1).
The path in a sockaddr_un is terminated either by a '\0', or by
the end of the sockaddr as defined by sun_len.
Previously, the code could write the "safety" '\0' beyond the end
of the sockaddr (sockaddr_un's need only be large enough to store
sun_len bytes), and writing into the the supplied sockaddr is bad
anyway.
them.
Sysinstall used to check /var/run/ld.so.hints (aout related) and create
hints with the ldconfig command, but the ldconfig command alone will
generate elf hints only. The correct behavior is:
* If /var/run/ld-elf.so.hints does not exist, generate elf hints
* If /var/run/ld.so.hints does not exist, generate aout hints
(using ldconfig with the -aout option)
This will help ports that check for aout libraries using ldconfig in their
pkg-req scripts.

- the changes that renamed libf2c to libg2c had not reached here
- there were no definitions for LIBDEVINFO, LIBMENU, LIBPANEL, LIBTINFO,
LIBUSB or LIBVGL. LIBUSB was used without it being defined, and
LIBDEVINFO and LIBVGL should have been used.
- the definitions of LIBDESCRYPT, LIBGCC_PIC, LIBGPLUSPLUS, LIBKZHEAD,
LIBKZTAIL, LIBSCRYPT and LIBSCSI were garbage.
Fixed some old bugs:
- LIBC_PIC and LIBCOM_ERR were assigned to using "=" instead of "?=".
- the definition of LIBC_R was disordered.
- LIBFORM was misspelled LIBFORMS (but not actually used).

fsck checking. Applying these changes (typically via mergemaster)
will cause your system to start running background checks on all
your soft update enabled filesystems (provided that you have
a kernel with the required functionality, e.g., one built since
the end of April). Please report any and all problems to
mckusick@mckusick.com (not mckusick@freebsd.org which I read
infrequently). See the comment above the fsck command in /etc/rc
for instructions on how to disable background checking should it
cause you too much trouble.
Several FAQs:
1) Can I reboot before the background checks are done?
Ans) Yes, when the system restarts the checks will pick up
where they left off.
2) Can a crash during checking corrupt my filesystem?
Ans) No, recovered resources are returned to the system using soft
updates which ensure that the freeing is done in a safe order.
3) How will I know if any background checks are being done?
Ans) Filesystems that are to be checked in background will be listed
as `DEFER FOR BACKGROUND CHECKING' at the usual fsck check time
during system startup.
4) What happens to the output of the background checks?
Ans) It is sent to syslog `daemon' facility log level `notice'.
5) When will this feature be available in the 4.X kernel?
Ans) Never. It is much too radical and extensive a change to be
MFC'ed. Besides, it needs many months of experience and
tuning before it is ready for widespread use.
6) What happens if a background fsck fails (i.e., fsck finds
errors that would normally require a manual fsck)?
Ans) The filesystem will be marked as needing a manual fsck.
At the next system reboot, the check will be done in
foreground and the usual actions taken (usually a failure
to go multi-user until fsck has been run by hand on the
affected filesystem).
