如果我们使用一个- (void)performSelector:(SEL)aSelector withObjects:(NSArray *)arguments
{
NSMethodSignature *signature = [self methodSignatureForSelector: aSelector];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature: signature];
[invocation setSelector: aSelector];
int index = 2; //0 and 1 reserved
for (NSObject *argument in arguments) {
[invocation setArgument: &argument atIndex: index];
index ++;
}
[invocation invokeWithTarget: self];
}
，它将把所有未使用的磁盘空间分配到一个卷。有人可以知道如果我们使用两个--grow选项会发生什么情况？
RHEL 7 kickstart文件：
