(If you can run a modified system built entirely from sources, I think you can do this.) However, this can't be done in -current because it breaks the statfs(2) syscall API, etc. There is a patch in projects/ino64 to try and change ino_t to 64bits and I think it also included changes for this. - It would need a new statfs(2) syscall and versioned library routines for everything that uses statfs(2) in libc, etc. So, for -current the answer is "it is not easy". There was a patch floating around that truncated the path to 64bits, so that the mounts are allowed but not reported correctly via statfs(2). You can probably find that patch and use it, if a broken statfs(2) isn't a problem for you. rick > Thanks > > Anton > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to > "freebsd-current-unsubscribe@freebsd.org" >
