=head1 ENVIRONMENT
|
||
|
|
|
||
|
|
If C<DAHDI_VIRT_TOP> is set in the environment, it will be considered
|
||
|
|
as a path to a directory that holds a dump (copy) of all the required
|
||
|
|
files from /proc and /sys . You can generate that directory using the
|
||
|
|
script C<build_tools/dump_sys_state> .
