usbimg2disk.sh fails in current

piratesmack · 11-17-2010, 09:48 AM

usbimg2disk.sh fails when trying to make the USB partition active with sfdisk. I think this is caused by the new default behavior of fdisk (DOS compatible mode=off, default display units=sectors)

I got it working again by replacing the sfdisk command with:

Code:

# Set the bootable flag for the first (and only...) partition:
lilo -A $USBDRV 1

I think it would also work to use fdisk commands 'c' and 'u' to switch back to the old behavior

Very well-debugged.
I think your "lilo -A $USBDRV 1" is the best option. I'll test later tonight.

I tested last night... and had no issues or errors. The unmodified script works fine on my laptop with 32-bit Slackware-current (with all the latest updates applied).

Hmm.
Did you use the '-f' switch so it recreates the partition table with the new fdisk?

Here's what happens when I run the script:

Code:

# sh usbimg2disk.sh -f -s /home/ftp/pub/Linux/Slackware/slackware-current -o /dev/sdc -l /tmp/usbimg2disk.txt

# We are going to format and use this device - '/dev/sdc':

# Units = sectors of 1 * 512 = 512 bytes
# Sector size (logical/physical): 512 bytes / 512 bytes
# I/O size (minimum/optimal): 512 bytes / 512 bytes

From the log file, here is sfdisk complaining about the partition table:

sfdisk: I don't like these partitions - nothing changed.
(If you really want this, use the --force option.)

attached is the full log file

I'll try a fresh install if nobody can reproduce this issue I'm having.

OK I tried a fresh install of the latest 32-Bit Current, and I'm still seeing the same issue.

Am I really the only one?

escaflown · 11-25-2010, 07:04 PM

I got the exact same error on a slackware64-current multilib install.

Thanks.

Glad I'm not the only one.
