Description Mads Kiilerich 2011-09-09 13:51:40 UTC

With livecd-tools-16.5-1.fc16.x86_64 I have started getting errors like 
  umount: /var/tmp/imgcreate-neqeMN/install_root/sys/fs/selinux/load: not found
after the livecd-creator image building has completed. The image works fine.

I haven't been able to figure out why - the code looks correct. My best bet would be if /sys/fs/selinux has been (lazily) unmounted before it tries to umount the fake load mount.

Comment 1 Henry Huang 2011-11-22 06:28:59 UTC

I also the same problem on the latest live-tools source codes.
http://git.fedorahosted.org/git/?p=livecd;a=summary
In the process of mount/umount, both have this error.
mount:  install_root/sys/fs/selinux/load: not exist
umount: install_root/sys/fs/selinux/load: not found

Comment 2 Brian Lane 2011-11-29 18:14:23 UTC

Do you have selinux enabled on the build host? Are you building an image with selinux enabled or disabled? It is probably some combination of those two settings.

Comment 3 Mads Kiilerich 2011-11-29 18:18:09 UTC

On the build host I have SE enabled but permissive (otherwise I get too many errors and don't trust the image).

I am building an image that has selinux --enforcing.

Comment 4 Brian Lane 2012-01-19 00:06:21 UTC

Does /sys/fs/selinux exist on the buildhost? And is there a line in the logs about skipping it? I suspect this is caused by a host/target mismatch of the selinux mountpoint. I'm seeing it on my F15 system with selinux disabled on the host.

Comment 5 Mads Kiilerich 2012-01-19 00:18:59 UTC

I don't have the machine right and can't give the full answer now, but:

SELinux do in general work fine on the host machine, so I assume /sys/fs/selinux is correctly mounted.

Which logs should mention any skipping and exactly how should the line look like? (I haven't noticed it and I assume I would have noticed it if it was a place I would look ... but that doesn't prove anything.)

I do however run updates-testing on the build host and only updates on the image I compose. The policy version might thus be "slightly" different. Do you expect that is enough to cause this?

Comment 6 Brian Lane 2012-01-19 18:31:16 UTC

It looks like this when I run with -v -d --logfile=build.log

Extending sparse file /var/tmp/imgcreate-VXruDL/tmp-aABXm_/ext3fs.img to 1073741824
Mounting /dev/loop3 at /var/tmp/imgcreate-VXruDL/install_root
Skipping (/sys/fs/selinux,/sys/fs/selinux) because source doesn't exist.
Retrieving http://mirrors.kernel.org/fedora/development/rawhide/x86_64/os/repodata/repomd.xml ...OK

A policy difference shouldn't be enough, it is the mountpoint that's having problems.
