It depends on if /export is in the same file system as /home currently is.
If the file systems are different, then make the new '/export' space.
Then use a tar-to-tar to copy the old home to the new place.
First, create the new directory situation.
If the file systems are different
mount /export (or whatever you have to do to create the new one)
cd /export
tar -cpf - /home | tar xpf -
If it is the same file system, just do:
mkdir /export (or whatever it takes to create the new one)
mv /home /export/.
(NOTE: Some versions of mv(1) (FreeBSD for example) will actually do a cp(1)
for you if they are not in the same file system so you can cheat a little)
Next you would have to modify each user's entry in the /etc/passwd
file to be /export/home/userid
rather than /home/userid
you can use vipw(8) to insert the export/ string in between the first '/'
and 'home' eg search for home and then insert 'export/'
By the way, I'd suggest not using the name /export. It gets used
in too many places to mean specific things and it could get confusing
some time later. Pick some other name.
