Usage: $0 [OPTION] command

Chroots into a specified LTSP chroot. Optional arguments can be provided to customize
the chroot location as well as extra mounts. If present, default arguments will be read
from the configuration file /etc/ltsp/ltsp-chroot.conf, and overwritten with used
command line options.

Options:
  -a, --arch[=ARCH]             Sets the architecture of the target chroot. Defaults vary by distribution.
  -b, --base[=PATH]             Sets base of target chroot. Defaults to /opt/ltsp if unspecified.
  -c, --mount-package-cache     If set, mounts the server package directories to the chroot previous
                                to chrooting. Settings vary by distribution.
  -d, --mount-dev               If set, mounts the server dev and devpts directories to the chroot
                                previous to chrooting.
  -h, --help                    Displays the ltsp-chroot help message.
  -p, --mount-proc              If set, mounts the server /proc to the chroot previous to chrooting.
  -m, --mount-all               If set, mounts the /proc, /dev and package directories to the chroot
                                before chrooting.
  -r, --copy-resolv-conf        If set, copies the server resolv.conf to the chroot previous to chrooting.
      --version                 Output version information and exit.
