Do I have to update the init thingy too or should it work without updating with each kernel upgrade? I would be going from a 3.1.5 to a 3.2.0-r1. While I am at it, I version my bzImages.

The other stuff normally doesn't change. Since most setups use modules, you could experience troubles... The other way would be - as you already proposed - to create an "init thingy" per kernel, eg initramfs-3.2.0-r1. If you use grub2 the grub2-mkconfig script searches for these (matching the name for your kernel image) and normally it works out of the box. FOr grub legacy (and lilo, i assume) you would need to make matching entries manually.

I keep saying I'm going to switch but . . . . . . . If you are using the new grub, how difficult is the switch? Scale from one to ten would be fine. 1 being pulling teeth and 10 a walk in the park and your eyes were closed. o_O I always keep a older boot line available so I will test this but I may version them anyway, just to be safe. At least I know there is a chance that it would work if the init thingy didn't build correctly. I tend to skip versions of kernels too. Sometimes I go several versions. Plus, honestly, I'm not even 100% sure I am booting the init thingy. I posted a thread about it but no replies. I'm about 95% sure tho that is is booting the init do hicky. Can you tell I'm not really liking the init thingy yet? Does the dracut init mount /usr if it is on a separate partition or do I have to set something to tell it too? Right now it's not but I do plan to redo my set up. I'm planning to put everything on LVM except / and its friends. Thanks. Dale :-) :-) -- I am only responsible for what I said ...

If you have trouble, you can reboot from a install cd/usb-drive and reinstall legacy grub. I never had any trouble with grub2 and I am using it since about 2 years, I think (at least no non-"handmade"-trouble ;) ). So I think it's easy. If you have a line for the init thingy in your grub.cfg it should use that or throw an error. If you use dracut according to a fedora-page you can add "rdshell rdinitdebug" to your kernel commandline and see dracut debugmessages and being dropped to a shell. maybe you could try that. Since I don't use dracut I'm not sure if it would mount a seperate usr. A quick google search seems to indicate that you have to do something manually: according to the last answer dracut tries to mount usr if init is a path in /usr - so you could create a symlink and add "init=/usr/bin/init" to your kernel commandline [1] - or use systemd (it should reside in usr, shouldn't it?).

Actually, I thought that was the point. Thing is, I'm not sure either. It seems when I built mine it read fstab. Maybe it looks there to see if /usr is on a separate partition and if it is then it knows to mount /usr. I dunno. I'll google some more tho. I followed a couple howtos to get mine to work. I'm not sure but I know one was on a Redhat or Fedora website. I think the others came from a dracut site. I just wanted to clear up some mud before I dived off into something. I'll check you link too. Thanks. Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words! Miss the compile output?

For future readers. There is a option called usrmount that tells it to mount /usr. That little sucker was hiding from me for the longest. I do wish dracut had some better docs. I may have to write a howto myself. If for no other reason than to remind myself how to make it work. lol Dale :-) :-) -- I am only responsible for what I said ...
