 Posted: Sun Aug 30, 2020 6:44 am Post subject: Mounting ISO image |
 |
|
Hi, ALL,
I want to mount an ISO image in order to install Windows 10.
However, trying to do so results in:
[ | Code: |
igor@IgorReinCloud ~ $ sudo mount -o loop ~/Downloads/Win10_2004_English_x64\(1\).iso /mnt/iso
Password:
mount: /mnt/iso: unknown filesystem type 'udf'.
|
but I have it turn on:
| Code: |
IgorReinCloud /usr/src/linux # cat .config | grep -i udf
CONFIG_UDF_FS=y
CONFIG_UDF_NLS=y
|
What am I missing?
Thank you. |

Hi,
I even installed "udftools", and still see the same error...
Thank you. |

So apparently there is a problem with the UDF implementation iin the kernel or there is no dependency that I did turn on..
I just built it as a module and got following::
| Code: |
IgorReinCloud /usr/src/linux # modprobe udf
modprobe: ERROR: could not insert 'udf': Unknown symbol in module, or unknown parameter (see dmesg)
|
Looking at the dmesg, I see:
| Code: |
[ 8467.978913] udf: Unknown symbol crc_itu_t (err 0)
IgorReinCloud /usr/src/linux #
|
Is there an option I need to turn on for UDF support?
Thank you. |

I know there is some magic needed to handle loop device correctly, but I have app-cdr/cdrtools installed to handle my ISO mounting.
Maybe this helps. |

ONEEYEMAN,
did you edit your .config manual (and then compiled the kernel) ?
If yes: Do it with "make menuconfig". This will set the correct crc-modules in library routiones automatically (you need at minimum " CRC ITU-T V.41 functions"). |

ONEEYEMAN,
Are you using your new kernel?
The date in is the build date of the running kernel.

No, I did use "menuconfig".

I thought that if you build it as a module you don't have to reboot.
I will see if that will help.
Thank you. |

ONEEYEMAN,
That's correct ... sometimes.
It depends what else you had to change and if the toolchain changed since the kernel was built.

NeddySeagoon,
Just to confirm - all I need is:
| Code: |
cd /usr/src/linux
make menuconfig
// confirm that the option for UDF is set as module
make && make modules_install
make install
reboot
|
And GRUB2 will pick up the new kernel and boot it up?
Thank you. |

Hi,
Apparently it doesn't.
This is before reboot:
| Code: |
IgorReinCloud /usr/src/linux # make install
sh ./arch/x86/boot/install.sh 4.14.65-gentoo arch/x86/boot/bzImage \
System.map "/boot"
IgorReinCloud /usr/src/linux # ls -la /boot
total 20312
drwxr-xr-x 2 root root 4096 Aug 30 13:06 .
drwxr-xr-x 21 root root 4096 Oct 21 2018 ..
-rw-r--r-- 1 root root 92216 Aug 30 13:06 config-4.14.65-gentoo
-rw-r--r-- 1 root root 92216 Aug 30 00:23 config-4.14.65-gentoo.old

IgorReinCloud /usr/src/linux # date
Sun Aug 30 13:06:51 CDT 2020
|
And after i rebooted:
| Code: |
igor@IgorReinCloud ~ $ uname -a
Linux IgorReinCloud 4.14.65-gentoo #2 SMP Fri Oct 12 23:43:43 CDT 2018 x86_64 AMD E-350 Processor AuthenticAMD GNU/Linux
igor@IgorReinCloud ~ $
|
What is happening here?
Thank you. |

That's not the boot you think it is.
You forgot to before you did the install.
There is no grub directory there and all those files dated Aug 30 hint that what you are looking at is the /boot directory on the root partition, not the boot partition that needs to be mounted there for kernel updates.
Grub and all your boot files are in the boot partition.

If you insist on a separate /boot, you should put "auto" inn the /etc/fstab parameters or use "defaults". The following example mounts /boot at bootup
| Code: | | /dev/sdb1 /boot ext3 defaults 1 2 |
If you worry about /boot being corrupted, tar up a backup. |

| IMO, one point of having separate /boot partition is to NOT mount it. /boot here is mounted ONLY when or during kernel change, and running the boot manager, and running backups. Otherwise it is not mounter. /etc/fstab uses the noauto option. |

Then be prepared for problems building a new kernel. |

Under the practice I've adopted, new kernel has a mix of automation and manual attention.
When I build new kernel (did this Saturday last), I do so with a script that includes mounting /boot and putting the new kernel there.
I do the boot manager stuff (lilo here) with /boot mounted, as well - if /boot isn't mounted, lilo throws an error message. The boot manager part is manual. This involves an edit of lilo.conf because I used version-named kernel file. /boot typically holds two working kernels.
umounting /boot is another manual step.
I manually edit a cruft exception file too, but that doesn't involve /boot. The kernel building script gives a concise reminder of things to be done manually. |

That's what is for. To detect those problems before they bite you in the bum.
I get it wrong sometimes. :)
