(I'm with CentOS 5.5 x86_64) 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. ////jerry > > Cheers, > Soo-Hyun > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos
