[CoLoCo] partitioning (after the fact...)

[Ryan Taylor]

Thanks again for the input.  I'll probably end up tackling the install this
weekend.  One last follow up question...:

I'll be creating the new /home partition in Edgy following the steps
here<http://www.psychocats.net/ubuntu/separatehome>.
One thing that is not mentioned is what happens during the install process
for future Ubuntus (gutsy in this case)?
When I tell it to use the existing /home partition as "/home" will it
reformat the partition?  ---I realize this probably doesn't happen since
that would defeat the purpose
of having a separate /home partition in the first place...

Or does the the installer just ignore the files and just assign the
appropriate permissions, links, etc to the existing files?  I just have some
important stuff in there I wouldn't want to lose.
Forgive me for being over-cautious...

Regards,
Ryan
