unfs-server: new userspace nfs recipe
This is a simple userspace NFS server, derived from one which was previously used in openSUSE 10.x. Wind River contributed many of the patches. This package is not intended for target installations, only -native and -nativesdk use. Enabling nativesdk for readline, sqlite3, and pseudo was required, as well as a few new autoconf siteconfig entries. Signed-off-by: Scott Garman <scott.a.garman@intel.com>

13+Thu Nov 9 17:03:05 2000
14+
15+ * No longer use OPEN_MAX
16+
17+ * Reworked configure.in, BUILD script no longer needed
18+ (nor functioning)
19+
20+ * Be more anal about matching cached fh's and real files.
21+ In addition to the psi, we also store dev/ino/type now
22+ and match that in fh_find.
23+
24+ * Write pidfiles
25+
26+ * Support nosetuid
27+
28+Wed Feb 9 14:52:34 2000
29+
30+ * auth_init.c didn't properly parse options--rot_squash
31+ which is obviously a typo was parsed as ro.
32+ Thanks to Jan Steffan for complaining about this :-)
33+
34+Mon Jan 31 11:48:34 2000
35+
36+ * Fixed Y2K bug in logging.c.
37+ Thanks to Jonathan Hankins <jhankins@homewood.k12.al.us>.
38+
39+Thu Dec 9 11:14:21 1999
40+
41+ * Fix handling of NFS-mounted and /proc directories.
42+ They weren't properly hidden.
43+ Thanks to Dick Streefland <dick_streefland@tasking.com>
44+ for the report and a first patch.
45+
46 Wed Nov 10 10:17:16 1999
47
48 * Security fix for buffer overflow in fh_buildpath
49 No thanks to Mariusz who reported it to bugtraq
50 rather than me.
51+
52+Wed Nov 09 17:10:00 1999
53+
54+ * Workaround for broken Solaris clients that can't handle
55+ atime/mtime/ctime of 0.
56+ Thanks to Frank Wuebbelin for his problem report and
57+ testing the fix.
58+
59+ * Fixed typo in exports.man
60+
61+Tue Nov 2 10:31:14 1999
62+
63+ * Patch for mode 0100 and 0100 executables by
64+ Michael Deutschmann <michael@talamasca.wkpowerlink.com>
65+
66+ * Common startup stuff for all daemons.
67+ Inspired by code sent to me by someone (sorry, I forgot
68+ your name, and the mail's gone!)
