With "memory boot" the "docache" option is activated in the cmdline. With this option the init process copies the sysrcd.dat file into the memory before mounting it as the root file system. So it takes a bit longer to start, but using it is faster, because no program needs to be loaded from disk, but thats more of an issue when booting from an optical disk drive. The main reason why I have this option here is because it allows you to overwrite everything on the harddrive, because your system is in the RAM.

And no, no option here allows you to make persistent changes to the SystemRescueCD. But if you like to do this, you might want to look into the available boot options[0]. The "backstore=xxx" seems to provide what you want. If you find settings that are useful for everyone and can be integrated into this package, message me and I will do so.

Out of curiosity, what's the difference between normal boot and (Memory) boot? Also, is it possible to permanently alter or make persistent changes to SystemRescueCD using either boot method?

I added more boot targets, but some aren't currently working (4.9.0-1) any improvement ideas are welcome.
(I currently don't have much time to do experimentations with it. Maybe at a later date.)

Also you can load the alternative kernel. Its the 3.14 version.

PyroDevil commented on 2014-09-25 23:46

Oh and you can't disable automount completly, because the kernel has to load the 'sysrcd.dat' file. So in your case the root partition has to be mounted.

You can configure the boot process in the '/etc/default/systemrescuecd' file.
You can and add 'nomdadm' to the boot parameters to disable the software raid.

I now added a variable for the boot base directory, so you have to specify "/boot" if you don't have a extra boot partition.

OK, that did it. Thank you. Here is what worked.

Tip? Add a kernel/boot cheat code (if available) to disable RAID autodetection and general disk automounting. System rescue CD is to repair/admin disks, not use them immediately. The detection and mounting attempts take a long time too.

The current SysRescCD kernel 3.10.X is pretty stale but I guess you're stuck with upstream releases.

He couldn't find 'sysrescue/sysrcd.dat' because the subdir kernel parameter is still wrong.
Try replacing 'subdir=sysrescue' with 'subdir=boot/sysrescue'.
If this works I can implement a configuration option for this case.

Voice commented on 2014-09-24 06:36

You are right, that is the error I saw. The disk has /boot on the same partition as everything else. I made the change you suggested. It worked but with other problems. At some stage the system rescue boot process says

!! Cannot find device with sysrescue/sysrcd.dat. Retrying...

and apparently loops in a retry cycle. I manually rebooted as I had already waited some time to see that much.

Thank you

I can boot the sysrescue without problem.
Do you have /boot on a seperate partition?
If not, that might be the reason.

But grub shouldn't throw '/systemrescuecd/rescue64 not found'. I should instead throw '/sysrescue/rescue64 not found', in case it has problems locating the kernel.

You might try to change all directories in '/etc/grub.d/25_systemrescuecd' from '/sysrescue/' to '/boot/sysrescue/', rerun 'grub-mkconfig -o /boot/grub/grub.cfg' and report your findings.
