FreeBSD dragonmini.dg 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Tue Aug 26 20:30:23 SAST 2008 root@dragonmini.dg:/tmp/usr/src/sys/GENERIC i386
>Description:
The system hangs when init chroot to a unionfs directory. This is a regression as 7-Beta did not have this problem
>How-To-Repeat:
Add the following to loader.conf:
init_script="chroot"
init_chroot="/base"
Have the chroot script do the following:
# mount -t unionfs -o noatime -o copymode=transparent /tmpfs /base
{where /tmpfs is a suitable unionable filesystem, such as ufs}
(please see attached for the output [via serial] of the boot [with the chroot file content])
>Fix:
Patch attached with submission follows:
OK more chroot
*** FILE chroot BEGIN ***
#!/rescue/sh
PATH=/rescue
trap 'echo Recovery console: ; PATH=/rescue /rescue/csh -i ; exit' 1 2 3 6 15
echo -n "Mounting compressed base:"
mount -t cd9660 -o ro /dev/$(mdconfig -a -t vnode -f /base.uzip).uzip /base
echo .
echo -n "Allocating temporary filesystem:"
mdmfs -s 32m md /tmpfs
echo .
echo -n "Overlaying temporary filesystem over base:"
mount -t unionfs -o noatime -o copymode=transparent /tmpfs /base
echo .
umount /dev
echo "Chroot to base..."
*** FILE chroot END ***
OK boot
