because diskless client, in the first place don't have hd,
so I copied from another ws that have already fedora installed
to /a/root

thank, that's solve my problem,
I have try your solution. I fault that specify nfs root with /a/root, the correct one is /a (directory
that countain root and snapshot dir), and directory for redhat-config-netboot should using
/a too, the help hint is confusing me, "enter nfs exported dir"-> nfs exported /a/root and /a/snapshot
and the problem nfs so slow(with error message still retrying), i dunno if this the real problem
I change/add ethernet 8139too with Full Duplex 100mbps, the old one is using tlan(half duplex 10mbps)
then just running well
now It's running well, until enter graphical boot
it show gdm login menu,
but gnome restart again when enter desktop, I found that because memory not enough
(diskless client compaq deskpro 6000, pentium pro, 65mb, S3 savage)
so I create swap file 256mb and set loop device for that(add script to rc.local)
so, /dev/loop0 swap swap defaults 0 0
but I think it's still slow,
what can I do to speeding up? or
just running xinit in diskless client then query from X in server?
but I still have one more problem,
cups don't want running
what list files that needed to cups running? so I can specify in snapshot/files
thank you,
and thank you to fedora too,
because I don't need add & download more packages to use diskless, and recompile kernel
so setup time will faster
