Sure, that exactly the point you can replace any existing field but if I want to include information about using graphic symbols on my teminal i.e. to make frames around a window - neither the standard termcap or terminfo supports this, but in termcap you could make new entries (provided you could find a two-letter code not already in use) however it is impossible in terminfo since it only allocates addresses (in the compiled entry) for known fields - which is why the tic command has been altered between SYSVR2 and SYSVR3 since more entries were added.

"cpio" thinks there is a 14 character size? Gee, that's news to me. Sun has supplied "cpio" with its systems for quite a while, and has had file systems without a 14-character file size limit for at least as long. The only changes made to "cpio" (until a lot of real grot was cleaned up recently) had nothing to do with the directory format; "cpio" doesn't even know what directories look like! As for "uucp", well, err, umm, there's this #define constant in the Honey Danber source to S5R3 called "BSD4_2"; presumably it wasn't just stuck in there for decoration. It may not *use* more than 14 characters of the file name, but it uses the directory library so it should be capable of surviving changes to directory names. COFF, unfortunately, thinks file names are limited to 14 characters (I presume this is the source of SGS's problem), but that's just a botch. You could stick longer file names in the string table, and just have first 4 bytes of the filename auxiliary entry be zero and the next 4 be a string table index. You missed the *real* killer, though; if he just redefined DIRSIZE to something other than 14, and recompiled the kernel, every single one of the file systems on his disks would be totally unusable by that kernel! DIRSIZE is in the "fundamental constants of the implementation-- cannot be changed easily" section of , with good reason. (Other items in that section, such as CLKTICK ("microseconds in a clock tick") and CDLIMIT ("default max write address", i.e. default "ulimit"), don't belong there at all, of course. The latter should, of course, be changed to 0x7fffffff or some other flavor of MAXLONG.)

These aren't described very well in older documentation, including that supplied with 4.3BSD, but they're at least mentioned in current versions, if I recall correctly.

Sorry, password aging doesn't exist in Ultrix (at least, in Ultrix 1.2 and 2.0). If you're really desparate for it, you can maintain a separate database of password aging information (system V keeps this info in /etc/passwd, it probably isn't a good idea to try this with Ultrix), have /bin/passwd update it every time a user changes their password, and have /bin/login check it on each login (this of course assumes you have sources).

The intention of grading in 4.3BSD was to keep phone bills down, not to reduce machine load. Hence, if a machine calls you and isn't picky about grade, then everything goes. But you can do what you want: run the slave uucico from a shell script with the appropriate options. We do this for news all the time. Something like: nuucp:xyzzyxyzzyxyz:6:1:UUCP Login:/usr/lib/uucp:/usr/lib/uucp/uugraded where the file /usr/lib/uucp/uugraded contains #!/bin/sh exec /usr/lib/uucp/uucico -gc Of course, the script can be as ellaborate as you like, checking the time and so on. One DANGEROUS security hole: if you run a shell script like this, then make sure that the home directory for the login is *NOT* uucppublic. Otherwise you will have a world-writable directory from which the shell may look for a login startup script.
