Package: live-installer
Version: 34
Followup-For: Bug #652946
Hi again.
Because tar process doesn't return ant error, apparently, I didn't try
to extract it's error output in my previous tests. When I did, by adding
someting like "2> /target/tar-errors.txt" in the "tar xv" line, the file
showed this
tar: can't remove old file ./var/lock: Is a directory
So the extraction is not completed and stops when extracting /var/lock
**and** does not return an error to live-installer. Maybe the exit code
of tar extraction process should be also be redirected to track future
errors while extracting the filesystem.
After trying to get busybox tar to exclude var/lock, without success
because tar in debian busybox does not handle exclude option, I've tried
the lenny approach I've seen in live-installer.postinst history in git
repo, and use live system installed tar to extract the filesystem
excluding var/lock.
chroot . tar c . --exclude=var/lock | \
(chdir /target && tar xv 2> /target/tar-errors.txt) | \
This gave me another error later upon install about /var/run:
tar: can't remove old file ./var/run: Is a directory
Then I added var/run to excludes, rebuilt udeb, rebuild live image and
the install worked without missing dirs and files, even the excluded
dirs were in /target/var. After boot no errors.
Patch attached.
Merry Christmas.
