Example

I posted an example of a chroot in a home directory. If you can complete it or correct it, please do. If you can't, please don't remove it.

The example has been modified from /usr/bin/bash to /bin/bash, even though:

$ which bash
/usr/bin/bash

How is it on your system, /bin/bash or /usr/bin/bash?

Very well, this is quite amazing:

$ ls -l /bin/bash /usr/bin/bash
-rwxr-xr-x 1 root root 713872 Jun  1 03:26 /bin/bash
-rwxr-xr-x 1 root root 713872 Jun  1 03:26 /usr/bin/bash
$ cmp /bin/bash /usr/bin/bash
$ echo $?
0

I changed this because you cannot use /usr/bin/bash as the user's shell (useradd -s command) in normal circumstances. The user would not be able to login because /usr/bin/bash is not in /etc/shells by default. In a chroot it may not matter (assuming the useradd command even works, I know chsh will not let you change to a shell not in /etc/shells but not sure about useradd), but there's no reason to use /usr/bin/bash and it can cause problems for anyone coming across the command and using it for something else. /bin/bash is the correct way to access bash is most circumstances.

Questions

  • Is it possible to have multiple Chroots on the same target device? --unknown
  • Is the "Run graphical chrooted applications" section really necessary? I have chrooted from an x86_64 distribution (Parted Magic) into my current i686 Arch system and running graphical applications worked just fine. All I had to do was to start them from the chroot terminal. Seems like an unnecessary piece of information to me. --DSpider (talk) 10:02, 19 August 2012 (UTC)
