baselayout-2 and openrc-2.2.0 have problems running nfsmount stop in case, when there are submounts into nfs directory of proc, dev, or other non-nfs filesystems. There is actually the same problem with baselayout-1 also. Here is an example of mounts within /chroot (nfs mount point) f9pc26 ~ # cat /proc/mounts|grep /chroot pikolit.ijs.si:/d0/sys /chroot nfs rw,vers=3,rsize=1048576,wsize=1048576,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=194.249.156.61 0 0 udev /chroot/slc4.x86_64/dev tmpfs rw,nosuid,size=10240k,mode=755 0 0 pikolit:/d1/nfs /chroot/slc4.x86_64/net/pikolit/d1/nfs nfs rw,vers=3,rsize=1048576,wsize=1048576,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=194.249.156.61 0 0 /dev/root /chroot/slc4.x86_64/tmp xfs rw,noquota 0 0 /dev/root /chroot/slc4.x86_64/etc/resolv.conf xfs rw,noquota 0 0 /dev/root /chroot/slc4.x86_64/var/spool/PBS xfs rw,noquota 0 0 proc /chroot/slc4.x86_64/proc proc rw 0 0 pikolit:/d0/nfs/grid /chroot/slc4.x86_64/net/brenta/d1/grid nfs rw,vers=3,rsize=1048576,wsize=1048576,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=194.249.156.61 0 0 pikolit:/d0/nfs /chroot/slc4.x86_64/net/pikolit/d0/nfs nfs rw,vers=3,rsize=1048576,wsize=1048576,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=194.249.156.61 0 0 AFS /chroot/slc4.x86_64/afs afs rw 0 0 /dev/sda4 /chroot/slc4.x86_64/data0 xfs rw,noquota 0 0 I did a dirty trick with /etc/init.d/nfsmount: ---- stop() { ebegin "Unmounting NFS filesystems" #AF while umount `cat /proc/mounts |grep /chroot|awk '{print $2}'` do echo "try umount chroot tree" done #AF umount -a -t nfs,nfs4 eend $? } ----- which is obviously not a good/general solution, but it works fine in my case. Reboot/shutdown is quick and does not hang for ages. Is there a better solution for that?
really it's going to be a problem regardless of baselayout and filesystem ... if you have any non-net based filesystem mounted below a net based filesystem, the unmounting isnt going to work. we attempt to do all net-based unmounts and then we attempt all non-net based unmounts. probably be the same problem while mounting too.
Closing per vapier's comment.
