Comment (by walter.huettenmeyer@…):
sorry for necrobumping.
just upgraded to chaos calmer trunk r44053 and had the same issue of
neither pivot overlay nor pivot root working.
Editing my fstab to mount the mtdblock<n> on a different location helped.
After several reboots it still mounts my sda1 as /overlay and I am happy.
Not sure if the delay_root is needed, but it didn't harm the boot
duration, so I'll leave it at 15.
{{{
config 'global'
option anon_swap '0'
option anon_mount '0'
option auto_swap '1'
option auto_mount '1'
option delay_root '15'
option check_fs '1'
config 'mount'
option tartet '/overlay-boot'
option device '/dev/mtdblock3'
option fstype 'jffs2'
option options 'rw,sync'
option enabled '1'
option check_fs '0'
}}}
After the first reboot and several other reboots it says:
{{{
root@router:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 238.1M 11.1M 223.0M 5% /
/dev/root 2.0M 2.0M 0 100% /rom
tmpfs 14.0M 452.0K 13.6M 3% /tmp
/dev/sda1 238.1M 11.1M 223.0M 5% /overlay

}}}
Router is a Linksys WRT160NL (ar71xx). Hope this can help someone.

external usb drive.
