I'm not sure how well it would do that, but it won't hurt to add. I'll have to put in a hard link and copy across devices and see if the hard linked files are hard linked on the dest dev. Thanks for catching that. I don't use hard links much... >...

I think so. I use rsync to synchronize samba shares and web sites between servers so I've gotten used to using it for other things. It also looks more like a copy, which might be easier to understand for those less familiar. I was considering adding the tar option. How does tar handle hard links? > At step 6, since everything has already been cleanly unmounted, should > just be able to hit the power button. Add something to the effect of > "Remove the rescue media before rebooting." I've added the cleanly unmounted / power switch aspect and moved the 'remove rescue media' to the booting back up portion of the testing step. Does that look better? I debated briefly with myself over suggesting they could simply power it off and had discarded it as not best practice. I'm reasonably happy with the compromise. I'll have to check if install / rescue has a shutdown command available... > That's all the comments I have without actually going through testing > the procedure.

Writing documentation is always a balancing act between not putting enough detail in because it seems intuitive to the person who does it every day and putting too much in with the effect of it being too pedantic. I like that the contents becomes a checklist for repeatable processes. Do you have a source for round tuits? I can only find finite sided ones... > Phil
