fstab not built properly after copy

[nicolasmdq]

Hi @DonyorM when I run weresync disk is copied successfully, but /etc/fstab is left with comments only.

Command line:

weresync -C -L grub2 -E 1 -g 2 --source-mask '{0}p{1}' /dev/nvme0n1 /dev/sda

/etc/fstab from destination disk:

# This file is generated by WereSync. All comments have been copied, but they have not been parsed.
# Any reference to identifiers during installation may be inaccurate.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p2 during installation

pip show weresync

When I use the same version in another machine copying from /dev/sda to /dev/sdb it works fine. Maybe using source-mask breaks /etc/fstab modification?

Thank you!

NOTE: Both source and destination disk has 2 partitions (So message "'Could not find device /dev/sda2" is strange):
