TinyCore on USB thumb won't mount .iso as loop device
« on: August 13, 2016, 06:37:23 AM »
I installed TinyCore 7.2 on usb thumb using the tc-install extension, tried to mount iso as follows:
mkdir /mnt/disk
mount -o loop name.iso /mnt/disk
Nothing happened and there is nothing in /mnt/disk.
mount --help says "-o loop" will be ignored and loop device autorecognized

Any ideas?

You could try:
Code: [Select]
$ sudo mount name.iso /mnt/disk

Did you get any error message? Are you sure that name.iso is a valid iso file?

Nothing from mount. I'm sure it's a valid iso 'cause I've tried it with my other live Linux cd and succeeded. (Of course name.iso is not the actual name, I'm just simplifying the question)

Does the fact that the iso file is on a ntfs partition ring a bell?

Maybe you could try this, just to be sure:
Code: [Select]
$ sudo mkdir /mnt/iso
$ sudo mount /mnt/sdb1/tmp/CorePure64-7.2.iso /mnt/iso
$ ls /mnt/iso/boot
corepure64.gz  isolinux/      vmlinuz64

There is no iso file on my sdb1 so I tried with the Tinycore-current.iso file I downloaded and burnt to cd(also on ntfs partition) and it worked!!
The one iso that failed me is Windows 8 Installation dvd image. It worked on my other live Linux cd which is MUCH larger and more fully loaded than TinyCore.

I loaded util-linux to replace busybox and tried mount again, it gives me error message "unknown file system type 'udf'".
Is there an app I can load to support udf? I tried searching for udf in the app browser and couldn't find any.
My search on internet suggest udf support should be built into the kernel, right?

Hi vincentyu1130
See if installing the  filesystems  extension helps.

Hi vincentyu1130
You're looking for an extension called  filesystems-4.2.7-tinycore.tcz.  The number in the extension name should match
the kernel you are running.
