This is correct. It was fixed, but due to breaking backward
compatibility, the broken behaviour was restored in order not to cause
problems to existing users (after a number of bug reports were filed
about it, and there was a lot of confusion on the user mailing list).
If you want proper quoting, you need to quote within quotes with
e.g. \".
From the current dchroot(1) manual page:
The command is one or more arguments which will be run in the
user’s default shell using its -c option. As a result, shell
code may be embedded in this argument. If multiple command
options are used, they are concatenated together, separated by
spaces. Users should be aware of the shell quoting issues this
presents, and should use schroot if necessary, which does not
have any quoting issues.
To avoid the quoting issues, schroot(1) behaves exactly as you want:
dchroot -c unstable -q -- /tmp/printargs normal a spaces "b c" dash -
dashletter -v dashes -- normalagain ee
argv[0] = "/tmp/printargs"
argv[1] = "normal"
argv[2] = "a"
argv[3] = "spaces"
argv[4] = "b"
argv[5] = "c"
argv[6] = "dash"
argv[7] = "-"
argv[8] = "dashletter"
argv[9] = "-v"
argv[10] = "dashes"
argv[11] = "--"
argv[12] = "normalagain"
argv[13] = "ee"
$ schroot -c unstable -q -- /tmp/printargs normal a spaces "b c" dash -
dashletter -v dashes -- normalagain ee
argv[0] = "/tmp/printargs"
argv[1] = "normal"
argv[2] = "a"
argv[3] = "spaces"
argv[4] = "b c"
argv[5] = "dash"
argv[6] = "-"
argv[7] = "dashletter"
argv[8] = "-v"
argv[9] = "dashes"
argv[10] = "--"
argv[11] = "normalagain"
argv[12] = "ee"
With schroot, we didn't have to worry about backward compatibility,
and so we could fix this correctly.

Roger
