Switching google's advanced search from "Anywhere in the page" to "In
the title of the page" you get links from

I should explain I work in Electronics, and have been continually
frustrated by others finding things I cannot. Often it's stupoid things
like pages that say they're in French when they actually are English,
and I specifying "English" as the language. Sometimes you just have to 
use the tools properly.

The biggest hitch with ide-scsi is /etc/fstab, IIRC. You have to select
it as ide-scsi, enable writing, and have udf(?), ide-scsi, generic scsi,
and probably more available to the kernel.

This you can probably fix. A lot of things reduce the path to
"/bin:/usr/bin;" I have also seen "/usr/bin:/usr/sbin;"No doubt it's a
security ploy but actually ends up being a pain in certain
circumstances. Try this

grep PATH /etc/* |less
grep PATH ~/* <as your cdwriting user>
grep PATH ~/.*

BTW, I have 'su' in /bin. Where is yours?

You will probably need the 'less' bit. I would advise against using the
-r option on grep for /etc!

You are nearly there with this one. Turn up debugging and check your
logs. Another thing to beware of is that if something wants to be a
user, and you run it as root, it may well fall back to being 'nobody'
the most useless of lusers. Read the small print with this package.

Gnome appears to be dependancy Hell.

Doesn't mkisofs do it? One thing you can do, btw, is make up your iso as
a block file and then mount it to check it.

Thank you for restoring our confidence in your hard work and diligence.

I haven't sorted this myself, you know. I mean to buy a cd or dvd writer
but it just never happened. The last one was robbed and returned
_with_5V_applied_ blowing it and a Southbridge :-O. Kids....grrr.
