Dear Members of the OSGeo mailing list,
in last days, I run the build process as described here [1] several
times to test our install script. Unfortunately the building always
failed due to problem with unmouting of dev and proc-filesystem for
chroot. After some small changes, I was able to fix this issue.
Do someone else also experienced those problems?
For me it is not obvious why it is necessary to bind the whole /dev into
the chroot - /dev/pts should do it. Secondly, it seems more safe to me,
to execute the mount of /proc outside the chroot.
After performing the following changes, building runs always fine in my
environment.
*build_chroot_debug.sh*
-- sudo mount --bind /dev/ edit/dev
++ sudo mount -t proc -o bind /proc edit/proc
++ sudo mount -o bind /dev/pts edit/dev/pts
...
-- sudo umount edit/dev
++ sudo umount edit/dev/pts
++ sudo umount edit/proc
*inchroot_debug.sh*
--mount -t proc none /proc
--mount -t sysfs none /sys
--mount -t devpts none /dev/pts
...
-- umount /proc || umount -lf /proc
-- umount /sys
-- umount /dev/pts
Any comments or ideas ?

Hi Patric,
Thanks for your patch, I will test it too.
The previous instructions came directly from the official Ubuntu wiki,
so we did not touch them, and it worked ok (we simply had to reboot the
build VM after a successful build process).
Best,
Angelos
