I noticed that : 1. it is a very good idea, 2. freefall is using it so I decided to do the same But, using nullfs gives me consistent panics like the following : Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0x0 code segment = base 0x0, limit 0xfffff, type=0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 58 (install) interrupt mask = panic: page fault Syncing disks 22 22 20 13 4 1 1 1 1 ..... 1 giving up I wanted to use nullfs to map /spare/usr/{src,obj} into "real" /usr/src and /usr/obj to get rid of the looong symbolic links like /usr/obj/spare/usr/src/lib/libtelnet... I got 9 panics between yesterday and tonight (eur. time). Ideas anyone ? I get these panics with both sunday and tuesday sources. -- Ollivier ROBERT -=- The daemon is FREE! -=- roberto@keltia.frmug.fr.net FreeBSD keltia 2.1.0-Development #15: Tue Feb 28 21:02:39 MET 1995
