Hello, I think nfs/netboot made sense when filesystem updates were being released for R2, but I don't really understand why anyone would use it anymore. Roach2 should soloboot by default, and unless you've compiled and are running a custom filesystem for some reason I'm not sure why any other boot method would be advantageous... Perhaps I'm missing something

My tutor suggests that I use Netboot. I spent a lot of time on netboot, the first time I used Ubuntu16, and this error occurred at netboot： [154620_8cc3a188_10952828.webp] I am currently trying to use Ubuntu14 for netboot and also getting an error about exportfs -a. I have also considered trying other boot methods, are there any related tutorials？All I can find is netboot. Thank you very much for your reply！ Wang Michael D'Cruze <[email protected]<mailto:[email protected]>> 于2022年6月8日周三 23:12写道： Hi Wang, 😬 I did use netboot for a while on my roach2 way back in the day, but it was easier especially following various updates to the board to just use soloboot. I hate to ask but is there a reason you need to use netboot? I assume you're using a roach2, and not a roach1?

I'm using ubuntu14.04. I had some problems setting up the ROACH netboot. * First, sudo apt-get install nfs-kernel-server nfs-common. * Second, sudo gedit /etc/exports,and add the lines: # Share 'roach_boot' directory/srv/roach_boot 192.168.100.0/24(rw,subtree_check,no_root_squash,insecure)<http://192.168.100.0/24(rw,subtree_check,no_root_squash,insecure)> * The last, exportfs -a * At this time, the terminal displays: sandang@wz-sandang:/etc$ sudo exportfs -a exportfs: No options for to NFS: suggest NFS(sync) to avoid warning exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "NFS:to". Assuming default behaviour ('no_subtree_check'). NOTE: this default has changed since nfs-utils version 1.0.x May I ask what are the reasons for these? I would be really appreciated if you reply!
