Hi Hackers,
Problem with /dev/null & /dev/zero inside a chroot:
I wanted to build a release from inside a chroot
( So /var/db/pkg matches what's required by make release,
without changing packages on outside the chroot, + Also to
experiment with
http://lists.freebsd.org/pipermail/freebsd-stable/2010-May/056705.html
)
Using 8.0-Release & amd64 I built a chroot,
(from memory, approx by:
cd /usr/src ; make world
setenv DESTDIR /usrb/chroot
cd /usr/src/etc ; make distrib-dirs
cd /usr/src ; make install
)
source `which unsetenv.csh` # remove my aliases etc.
chroot /usrb/chroot
cd /dev
rm null zero ; mknod null c 0 31 ; mknod zero c 0 32
cd /usr/src ; make
make: cannot open /dev/null.
"/usr/src/Makefile", line 111: warning: "/usr/bin/env
-i PATH=/sbin:/bin:/usr/sbin:/usr/bin make
__MAKE_CONF=/etc/make.conf -f /dev/null -V

*** Error code 1
cd /dev/
rm null zero ; touch null
cd /usr/src ; make
Runs OK to here
===> sys/boot/i386/boot2 (all)
dd if=/dev/zero of=boot2.ldr bs=512 count=1
dd: /dev/zero: No such file or directory
*** Error code 1
What sort of null & zero should be in chroot ?
man mknod ... deprecated ...
Should I be running a devfs (I'm not currently)
Or a jail ? (I dont really want that level of encapsulation ).
Cheers,
Julian
