Hello,
Would it be possible for overlayfs to support being mounted with an
upperdir on an ecryptfs filesystem?
andin@box:~$ mkdir lower upper work merged
andin@box:~$ sudo mount -t overlay overlay -o
lowerdir=$HOME/lower,upperdir=$HOME/upper,workdir=$HOME/workdir merged
mount: wrong fs type, bad option, bad superblock on overlay,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
andin@box:~$ tail -n 1 /var/log/syslog
Feb 21 18:57:01 box kernel: [ 5323.931064] overlayfs: filesystem on
'/home/andin/upper' not supported as upperdir
andin@box:~$ mount|grep " / "
/dev/sda2 on / type ext4 (rw,relatime,errors=remount-ro,data=ordered)
andin@box:~$ mount|grep home
/home/.ecryptfs/andin/.Private on /home/andin type ecryptfs
(rw,nosuid,nodev,relatime,ecryptfs_fnek_sig=11c07678abb13aac,ecryptfs_sig=b1d3451eeea22381,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs)
Thanks,
- Andin
