Subject: [PATCH 30/32] fix(squash-lib): harden against empty $initdir
|
|
|
|
The postinstall phase of 99squash-lib has the potential to delete the
|
|
whole rootfs if $initdir is empty. This should(tm) never happen.
|
|
Nevertheless as the consequences are so devastating it is better to
|
|
double check.
