Re: [cobalt-users] CMU (miagration question)

[cobalt@xxxxxxxxxxxxxxxx]

Hey John,
Thank you for all the useful help and your notes!

I was wondering if email gave you any trouble as I saw in the
CMU manual that the mail spool is not moved, but moves the mail 
to the user home directory. Is a new mail spool then created with the
propper sym links to the home directories as the siteIDs are recreated on
the new webraq?

Also, I wonder how the CMU tool makes the sites so small. I.E- the /home
partition uses 800Megs and after I cmuExported it the export directory was
200Megs. I didn't think tar and gz could compress at that ratio! Not
complianing, hope it works :)

Hope this makes sense and thanks again!

Ashby
