该选项只对 Linux 系统镜像有效。<br/>
|

默认情况下，受Linux内核相关功能的限制，对于Linux系统，在启动后无法继续访问ISO文件所在的分区。在mount的时候会提示 device busy。<br/>
|
||||
如果这里选择 1，则 Ventoy 会尝试通过一些特殊的手段绕过内核的这个限制，但是这个功能是实验性质的，没有经过大规模和长时间的验证。

|
||||
This option is only avaliable for Linux distro image files. <br/>
|
||||
|
||||
By default, the image partition where the ISO files locate can not be accessed after boot. When you try to mount it you will get device busy error.
|
||||
This is due to linux kernel restriction (device-mapper module).<br/>
|
||||
If you select 1 here, Ventoy will try to bypass the restriction with some special mechanism.<br/>
