If I start the installation with manual network config, the problem persists: YaST does not start. When switching to another terminal, I can run ifconfig and ping my NFS server successfully. There are no useful logfiles available at this stage, /var/log/YaST is empty, /var/log/boot.msg does not show any errors. See attached the output of VT3.

It looks like it's hung in clntudp_create(). It does the address checking with a bunch of inet_pton calls and then moves on to the clntudp_create call, which never completes. 1 clntudp_create(0xaddr, 10005, 1, 3, 1 SYS_socket(2, 2050, 17, 7681) = 11 1 SYS_open(0xaddr, 0, 438, 0xaddr> = -2 1 SYS_futex(0xaddr, 128, 2, 0 <hung> The 0xaddrs don't matter yet since it's all in a shared libary anyway. I'll do some more digging. Perhaps someone involved with linuxrc development can shed some light on why we're not just calling mount(8) with mount.nfs(8) installed instead of essentially open coding it inside linuxrc. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The hang from comment #1 has disappeared, but now NFS mount fails because the initrd is missing /sbin/mount.nfs and /sbin/mount.nfs4.
