processing of /etc/ld.so.conf in ld.so itself (rather than in /etc/rc):
- added do_conf function and call to it in main to implement internal
processing of /etc/ld.so.conf
- moved maintenance of dir_list to dodir, with an added argument to
dodir to specify whether dir_list should be updated
- added option '-c' to suppress processing of /etc/ld.so.conf
- added option '-S' to suppress processing of std directories (but not
/etc/ld.so.conf)
- modified option -s to suppress processing of _both_ std directories
and /etc/ld.so.conf (i.e., it is equivalent to -cS)--this was done
so that users and scripts that interpret -s as meaning "process
only directories specified on the command line" would not be
startled
From PR #4031. One change was not committed, since it was unnecessary
(option variables are in the BSS, and do not need to be initialized to
0 explicitly).
Plus one change from me:
- getopt() returns -1 when completed, not EOF.
-i no longer implies -u, -i now does not use the entire first track
because some BIOSes refuse to boot from a partition in the first track.
-s renamed to -S, new -s for non-interactive setting of a partition's
id, offset and size. Updated documentation to match.
macros.
2) Clean up some gratuitous uses of write() instead of fprintf()
3) Clean up some of the alternative shell code in single_user(),
fixing a couple of bugs in the meanwhile. Also, fix pr-2620 from
Chris Demetriou -- when an alternative shell is exec'ed, it is now
not called "-sh" automatically.
4) rename the DEBUGSHELL option ALTSHELL since its almost always used
in NetBSD.
Notes:
1) It isn't clear that the ALTSHELL code is really ever very useful,
but we seem to have decided to always enable it anyway.
2) The code in init really needs an overall cleanup, but I just don't
have time or energy.
