GNU/Linux Bootable ISO - Prevent automatic reboot ?
Is there a way to prevent a the ISO from automatic reboot (so that I can read a report of what was SUCCESFULLY and FAILED installations?)
Or, when booting from a R/W media (USB, not iDRAC virtual optical), is there a way it can write a log file of the session (Labeled with the Service Tag, RTC date) ?
Thanks and have a safe weekend! ~Brian

Hello,
On the Create a smart bootable ISO directions:
Step 8: Select Reboot system automatically checkbox, when required
Can you leave that unchecked and test results?

I've been through config.json and configuation.xml and every menu in the GUI; I do not see this option.
The URL you've posted/shared in 404

Hi, I've also couldn't reach the link. However please take a look these two links below:
How to create a SUU (Server Update Utility) and a bootable ISO file within DRM | Dell US
PowerEdge: How to Create a Bootable USB Device with Rufus for Updates | Dell US
Hope those help!

I see the option you're mentioning, but it is only available in the "Export" feature, which makes a Windows compatible ISO not for booting.
As per the title, the question was related to the BASH shell / python scripts running within the GNU/Linux LiveCD Image ("Platform specific bootable ISO" feature)

If you're booting from a USB drive, one workaround might be to modify the update script so that it writes logs to a mounted storage location like
/mnt/usb
. You could add a line like :dmesg > /mnt/usb/$(dmidecode -s system-serial-number)_$(date +%F-%T).log
This way, you’d capture the system log with the service tag and timestamp, which should make it easier to review results after the process completes—especially if the system reboots automatically.

@Kenneth_R Thanks. Hopefully the Dell/EMC product development team for this product hasn't been fired (made redundant) and can make these small cosmetic improvements. And update to a new ISO based on GNU/Linux kernel v3.x and SecureBoot loader GRUB
