Hi, I noticed that when I first use mount.aufs for the first union, it replaces the soft link /etc/mtab with a real separate file /etc/mtab. Meaning, the /etc/mtab is no longer a soft link now and two lines get added for the single mount and the last line has extraneous characters: Here are the contents: none /bin aufs rw,xino=/.aufs/bin/.aufs.xino,br:/.aufs/bin=rw:/bin=ro 0 0 none /bin aufs \\015w,xino=/.aufs/bin/.aufs.xino,b\\015:/.aufs/bin=\\015w:/bin=\\015o 0 0 (I guess for every 'r' in either "rw" or "ro", there is a \\015 ) After the two more mounts, the /etc/mtab file gets more corrupt ( the lines appended and the format ). o 0 0n=\134=\134n/.aufs.xino,b\134 o 0 0in=\134=\134n/.aufs.xino,b\134 aufs 0 034 aufs 0 034 /proc/mounts file's contents seem OK. I'll mail the debug output of mount.aufs shortly. Thanks, Nitin. ------------------------------------------------------------------------------
