Package: debianutils Version: 4.3.2 Severity: normal When I create a chroot the ischroot command fails to detect it and returns an error code. It is good to return an error but since the purpose of ischroot is to detect if it is running in a chroot the result is not useful.
To recreate the problem I recommend a throwaway VM instance because the result is a slightly broken system due to an initscripts bug. * Create a Squeeze chroot. # mkdir /srv/chroot # cd /srv/chroot # debootstrap squeeze squeeze-test http://ftp.us.debian.org/debian * Configure policy-rc.d to avoid starting any daemons in the chroot. # cd squeeze-test # printf '#!/bin/sh\nexit 101\n' > ./usr/sbin/policy-rc.d # chmod a+x ./usr/sbin/policy-rc.d * Ensure that it is up to date. # chroot $PWD su - # apt-get update # apt-get upgrade * Upgrade it to Wheezy. # sed --in-place s/squeeze/wheezy/g /etc/apt/sources.list # apt-get update # apt-get upgrade # apt-get dist-upgrade At this point the system has two problems. One of them is that 'ischroot' cannot determine that it is in a chroot. # ischroot ; echo $? 2 As to how to fix this I have no good ideas. I did not look at the ischroot source and do not know what method it uses. I am only chasing this due to the problem with the initscripts process for /run migration and this is the earliest problem that I found. (Hint to others: To avoid the initscripts problem replace ischroot with /bin/true between the upgrade and dist-upgrade steps.) I can only think of using the inode of the root filesystem for detection. In the chroot: # ls -ldogi / 126483 drwxr-xr-x 22 4096 Aug 15 23:30 / ^^^^^^-- inode number is not 2 On the host system outside any chroot: # ls -ldogi / 2 drwxr-xr-x 21 4096 Aug 15 07:02 / ^-- inode number is usually 2 Outside the chroot the inode of the root filesystem is usually 2 for traditional Unix filesystems and for ext2, ext3, ext4. But I do not know about others. Thanks, Bob -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
