On a Mint 19 Mate pen drive persistent setup, I attempt to copy the casper-rw persistent file limited to 4GB to an ext4 partition.
I am looking for the steps to transfer applications and data to an xt4 casper-rw partition and boot it from the pendrive.
Steps so far:
I have created an ext4 partition named casper-rw
I copied all casper-rw files using
rsync -r -p -o -E
I removed casper-rw from the pendrive.
I rebooted counting on the ext4 casper-rw partition getting priority over the casper-rw file. The ext4 casper-rw partition appeared as casper-rw but was accessed as /casper-rw1.
On reboot there was one "cow format specified as overlayfs and no support found" error.
A second reboot brought Mint back with the ext4 casper-rw partition now mounted as casper-rw while the casper-rw file partition was also accessible.
On the next reboot expecting to boot using the ext4 casper-rw partition, "cow overlaysfs" again.
Removing the casper-rw file or backtracking to a previous casper-rw saved file resulted in the same error.
casper-rw ext4 partition could not be renamed by Windows EaseUS Partition Master. Using SystemRescueCd iso loaded on YUBI I was able to use gparted to change the ext4 casper-rw partition name.
Now I am back up with the casper-rw file mounted.
What I can try to move forward?
