Thanks to Russell Page for a quick response and a detailed and accurate answer to my first question, which did the job perfectly! No one answered my second question about the security implications of modifying chown to allow users to give away ownership of their files.

You can change many kernel variables on the fly with adb(1): $ su Password: # adb -w -k /dev/ksyms /dev/mem physmem 79a4 rstchown/D rstchown: rstchown: 1 rstchown/W 0 rstchown: 0x1 = 0x0 rstchown/D rstchown: rstchown: 0 ^D # exit $ ls -l foo -rw-r--r-- 1 russell staff 0 Nov 26 09:31 foo $ chown root foo $ ls -l foo -rw-r--r-- 1 root staff 0 Nov 26 09:31 foo $ "rstchown/D" prints the current value as a decimal number. "rstchown/W 0" sets the value to zero. You can only change values if you start adb with the -w option. You should change /etc/system anyway, so that the variable is set after your next reboot. A useful reference is the "Solaris Tuneable Parameters Reference Manual". http://docs.sun.com/app/docs/doc/806-4015 -- Russell Page. _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Thu Nov 25 19:47:31 2004
