I thought maybe this could be related to debootstrap, but I was not sure. Below I have made a comparison of the base-files package on two containers LXC I created from scratch for the purposes of these tests: root@sirius:~# lxc-ls --fancy | egrep "jessie|wheezy" jessietest RUNNING 10.1.0.49 - NO wheezytest RUNNING 10.1.0.32 - NO ------------------------------------------------------------------------ root@jessietest:~# lsb_release -a No LSB modules are available.

But if I do the same check on this notebook installed using the netinstall CD, permissions are not 755 but 775: viper@orion:~$ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 8.5 (jessie) Release: 8.5 Codename: jessie viper@orion:~$ ls -ld /bin/ drwxrwxr-x 2 root root 4096 jul 9 09:06 /bin/ Here I find a pattern, since the difference of permissions mentioned in the previous mail was found in a KVM virtual machine installed using the netinstall CD. But I have checked in other Jessie virtual machines and permissions are 755. So I'm not sure what can be introducing this difference. I just installed Jessie using the latest version of netinstall I have (debian-8.1.0-amd64-netinst.iso) and I can confirm here that /bin has permissions 775. So it may be that the problem comes from that side... Could you please confirm this? Anyway, I will try to make a test with the latest version of netinstall. > I don't know what exactly jailkit does to create a chroot, but since > AFAIK it's not packaged for Debian jessie, this could not be a bug > in the Debian distribution at all. > > Please tell us a step by step recipe to reproduce this problem (not > just what you remember doing the last time, but something that works > when you start from scratch) and why do you think it is a bug in the > Debian distribution and maybe we could help. I think jailkit fails when copy /bin using 775 from the base installation. I will try testing with Jessie netinstall 8.5 to see if we can isolate the source of the problem.
