[Libguestfs] newlines with write-append

Silly bash scripts have stuff like below to get things done, but equally silly guestfish scripts fail to add the required newline. Why is that? echo "$dev1 $mnt1 $fs $opts 1 2" >> /etc/fstab echo "$dev2 $mnt2 $fs $opts 1 2" >> /etc/fstab write-append /etc/fstab "$dev1 $mnt1 $fs $opts 1 2" : \ write-append /etc/fstab "$dev2 $mnt2 $fs $opts 1 2" : \ Even adding variants of \n does not help. Simple testcase: write /etc/fstab "#\n" : \ write-append /etc/fstab '#1\n' : \ write-append /etc/fstab '#2\\n' : \ cat /etc/fstab : \ quit ... libguestfs: trace: cat = "#\n#1\n#2\\n" #\n#1\n#2\\n libguestfs: trace: shutdown ... I guess using "sh" will be my workaround. Olaf
