DHCP and NFSroot/TFTP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

for the case someone uses DHCP for her/his network configuration in Barebox,
there is a race with the setup of some variables used for the NFS root.

The following patch fixes it, but maybe there are better solutions than that.

------------------------------------------------------------------------------

Setting up NFS root/TFTP related variables is successfull only if the network
interface is already configured. For the case someone is using DHCP, this
fails, because all these vars are still empty. Changing the order when the
DHCP is done solves the issue.
