Log:
When a machine boots the NFS mounting script is executed after
interfaces are configured, but for many interfaces (e.g. all Intel)
ifconfig causes link renegotiation, so the first attempt to mount
NFS always fails. After that mount_nfs sleeps for 30 seconds, while
only a couple seconds are actually required for interface to get up.
Instead of sleeping, do select(2) on routing socket and check if
some interface became UP and in this case retry immediately.
At least on i386, this causes a -Werror warning:
sbin/mount_nfs/mount_nfs.c:549:10: error: cast from 'char *' to 'struct
if_msghdr *' increases required alignment from 1 to 4 [-Werror,-Wcast-align]
ifm = (struct if_msghdr *)buf;
^~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
In practice I don't think the buffer can ever get misaligned, so can you
please add a NO_WCAST_ALIGN= to the Makefile?
