re-work of debs, config, scripts handling, according to issue #715
- debs, config and scripts are always searched and read from the
same place ($dcs-dir). Which place this is varies, depending on
GRMLCFG, noautoconfig and myconfig.
- debs are searched in $dcs-dir/debs. If debs=foo is given, foo is
taken as a shell wildcard for the debs being installed, paths are
allowed and relative to $dcs-dir.
- config archives (config.tbz) are searched directly in $dcs-dir. If
config=foo is given and foo is a file, that file is unpacked and its
content taken as configuration archive. If config=foo is given and foo
is a directory, the contents of the directory tree is copied over the
live CD configuration. paths are allowed and relative to $dcs-dir
- scripts are searched in $dcs-dir/scripts. If scripts=foo is given
and foo is a file, that file is executed. If scripts=foo is given and
foo is a directory, all files inside that directory are executed.
Paths are allowed and relative to $dcs-dir.
- If no GRMLCFG partition is found and noautoconfig is _not_ given
on the command line, nothing is changed and the dcs files are
searched within the .iso, $dcs-dir is set to the root directory
within the .iso
- If a GRMLCFG partition is found, $dcs-dir is set to the root of
the GRMLCFG partition unless noautoconfig is set. If noautoconfig is
set, $dcs-dir is set to the root directory within the .iso.
- If myconfig=foo is set on the command line, $dcs-dir is set to
foo, even if a GRMLCFG partition is present.
