Hello, Here below are the corrections of "df" usage in fai and make-fai-nfsroot. According to information from "info coreutils" if we used "df" without portability option (-P) and the mount device name was more than 20 characters long then the mount device name is put on a line by itself. And this breaks the logic of the part of the fai scripts which "check if target directory is mounted with bad options".
debian:~# info coreutils 'df invocation' `-P' `--portability' Use the POSIX output format. This is like the default format except for the following: 1. The information about each file system is always printed on exactly one line; a mount device is never put on a line by itself. This means that if the mount evice name is more than 20 characters long (e.g., for some network mounts), the columns are misaligned. 2. ... These are proof steps: debian:~# df -a Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/debian-root 3648584 846112 2617128 25% / tmpfs 127372 0 127372 0% /lib/init/rw proc 0 0 0 - /proc sysfs 0 0 0 - /sys udev 122444 88 122356 1% /dev tmpfs 127372 0 127372 0% /dev/shm devpts 0 0 0 - /dev/pts /dev/sda1 233335 26914 193973 13% /boot nfsd 0 0 0 - /proc/fs/nfsd debian:~# df /srv/fai/nfsroot/live/filesystem.dir Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/debian03-root 3648584 846112 2617128 25% / debian:~# df /srv/fai/nfsroot/live/filesystem.dir | tail -1 3648584 846112 2617128 25% / debian:~# df /srv/fai/nfsroot/live/filesystem.dir | tail -1 | awk '{print $6}' debian:~# debian:~# df -P /srv/fai/nfsroot/live/filesystem.dir | tail -1 | awk '{print $6}' / debian:~# Index: bin/fai =================================================================== --- bin/fai (revision 6121) +++ bin/fai (working copy) @@ -225,7 +225,7 @@ FAI_ROOT=$(cd $FAI_ROOT;pwd) # check if target directory is mounted with bad options - fs=$(df $FAI_ROOT | tail -1 | awk '{print $6}') + fs=$(df -P $FAI_ROOT | tail -1 | awk '{print $6}') if mount | grep "on $fs " | awk '{print $6}' | egrep -q "nosuid|nodev"; then echo "Target directory is mounted using nosuid or nodev.
