shrink-backup v1.3

• New options:
  • -q|--quiet mode. Mute rsync output
  • --no-color mode. No colorization in script
  • --rsync. User will get presented with the rsync line that will be ran and can modify it
  • --chroot option to access an image in a chroot environment (systemd-nspawn) to for example update/install packages or rebuild initramfs. Only works from the system you created the img
• Autoexpansion for operating systems:
  • Kali-arm
  • Ubuntu-server-arm (Ubuntu autoexpands by default, but that can be disabled with -e option)
• UI tweaks
• Removed check for .img extension when using --loop so it works on other img formats (for example .iso)
• Changed the dd line to use conv=fsync instead of sync and added a sync operation after dd is done to try to mitigate the "can not set loop paths" problem that some users experience
• User confirmation now require to also press enter after y/n
• Added /snap/* in exclude.txt and to be excluded as default if not using the exclude file
• Implemented a lock file that makes it impossible for boot partition to become unmounted during shrink-backup
• Nested btrfs subvolumes can now be added & removed in an update (-U)
• New way of excluding subvolumes for btrfs (exclude_btrfs.txt or shrink-backup_btrfs.conf depending on how you installed, see README for information)
• --fix now also adds option --fsync to rsync

Note

If you have made changes to exclude.txt and you used git to install, git pull will fail due to conflicts.
The easiest way to resolve this is to make notes of the paths you added, then:

git reset --hard
git pull

Then add your edited paths back into exclude.txt at the end of the file again.
