 |
|
| I have more 600+ ISO files, and want to mount them in dirs, but I found that Gentoo system can only mount 256 ISO files, is it restrict of the kernel? How can I change the kernel for mount the all ISO files? |

I'm afraid you're going to be limited by 256, though I may be wrong.
What is happening here is that, each time you mount an .ISO, you are using a loop device. See | Code: | | /usr/src/linux/Documentation/devices.txt |
and search for the word 'loop'. Also .
In Unix, all devices are numbered with a major number and a minor number. For loops, it is major #7. Minor numbers go from 0 to 255. Hence limited to 256 loops. |

So it looks I cannot mount my 600+ ISO files...

Yep, looks like it - I'd suggest you write yourself a bash script or ncurses program that allows you to easily mount/umount what you need at the moment  . |
