[SOLVED] Slackware 14 RC5 install image has a typo in boot up message

The install image has a small typo when first bootup. This is from the usbboot.img, I did not try the other.

It says:

Quote:

In a pinch, you can boot your system from here with a command like:
boot: huge.s root=/dev/sda1 rdinit= ro

Where rdinit should be initrd to avoid loading the initrd image.

I thought it always said rdinit?

That is not a typo. From /usr/src/linux/Documentation/kernel-parameters.txt

Code:

	rdinit=		[KNL]
			Format: <full_path>
			Run specified binary instead of /init from the ramdisk,
			used for early userspace startup. See initrd.

It's rdinit. I always used that when fixing broken Slackware installations.

Yes, kind of interesting... for example, if you are using an initrd.gz in lilo.conf:

boot: vmlinuz rdinit=/bin/sh

This runs /bin/sh inside the initrd instead of the usual /init script. This gets you a sh shell and nothing that /init normally does happens at all. Then, you can fix something maybe, and manually run /init (exec it so it is pid 1):

exec /init

Then, the system starts normally.

But, "rdinit=" tells the kernel to ignore the initrd and skip along with regular "legacy" boot of the root= device.

That is something interesting to know. As in my case, I don't need the extra support from initrd, so I used initrd= to skip the loading of it.
