Hallo Klaus,
> Was hat schroot mehr als chroot?
In der Paketbeschreibung zu dchroot steht ein bisschen was:
NOTE: the schroot package provides a better implementation of
dchroot. In particular:
* dchroot quoting issues are not present. dchroot runs commands in
the chroot with -c option of the user's default shell; when
multiple command options are used, the options are concatenated
together, separated by spaces. This concatenation breaks shell
quoting.
* schroot implements fine-grained access controls based on users
and groups, either of which may be granted the ability to gain
root access to the chroot if required.
Using schroot will avoid these issues, as well as provide additional
functionality dchroot does not possess.
