Subject: please change fallback shell handling

Date: Sun, 20 May 2012 21:50:52 +0200

Package: schroot
Version: 1.4.19-1+squeeze1
Severity: wishlist

Hi,

if a user's shell is not available in the chroot, schroot falls back to
/bin/sh.

That's probably ok for scripted stuff, but as an interactive shell dash
/bin/sh is often quite limited.

Please allow changing the default fallback shell in a config file, or
just try bin/bash before bin/sh?

Cheers,
weasel

Fixed in git for 1.5.3.  From the docs:

       -s, --shell=shell
              Use shell as the login shell.  When running a login shell a num‐
              ber of potential shells will be considered, in this  order:  the
              command  in  the SHELL environment variable (if --preserve-envi‐
              ronment is used, or preserve-environment is enabled), the user's
              shell  in  the ‘passwd’ database, /bin/bash and finally /bin/sh.
              This option overrides this list, and will use the  shell  speci‐
              fied.   This  option also overrides the shell configuration key,
              if set.

       shell=shell
              When  running a login shell a number of potential shells will be
              considered, in this order: the command in the SHELL  environment
              variable  (if  --preserve-environment is used, or preserve-envi‐
              ronment is enabled), the user's shell in the ‘passwd’  database,
              /bin/bash  and  finally  /bin/sh.   This  setting overrides this
              list, and will use the shell specified.  It  may  be  overridden
              using the --shell option.

Prerelease version at http://people.debian.org/~rleigh/schroot-1.5.3.tar.xz
This also includes the groups warning fix.

Hope this meets your needs.


Regards,
Roger

Changes: 
 schroot (1.5.3-1) unstable; urgency=low
 .
   * New upstream development release.
   * dchroot:
     - Always use "/bin/sh -c" to run the specified command, rather than
       the user's shell, in order to ensure consistent behaviour.
   * schroot:
     - Add shell fallbacks (Closes: #674040).  When running a login
       shell, try $SHELL (if preserving the environment), or else passwd
       pw_shell, then /bin/bash and finally /bin/sh.  This may be
       overidden using the shell configuration key, which may in turn be
       overidden by the --shell option.
     - Don't warn the user about groups which do not exist
       (Closes: #674041).  This is now debug log info only.
     - Add support for running programs in non-native architecture
       chroots using binfmt support for qemu user binaries
       (Closes: #604268).  Thanks to Loïc Minier, Julian Andres Klode
       and Colin Watson.
