I have been looking into making a small "rescue" image which I can boot into on a few servers which we have already installed in our business.
The root problem is, I have a 100M ISO which takes 20+ minutes to boot up using an ILO (I think there's a firewall somewhere and the firewall team is extremely unhelpful) and so I thought I would place the initrd.img on the local /grub partition.
The second problem is that /boot is only 100M in size, and we like to keep 2 kernels on it.
*SO* I'm looking at things like DSL (50M), possibly looking into trying to custom-create an initrd.img file, or something.
But I do recall reading an article sometime about putting a rescue image into your grub config - but I can't find it for the life of me - plus I'm not sure I'm doing the right thing at all.
Is there any advice you guys can give me, apart from the obvious "increase your /boot" or "get a better network admin team" ?
