DOC_CONTENTS="Please adapt /etc/squashmount.pl as well as
/etc/systemd/system/squashmount.service.d/timeout.conf to your needs.

Configure the mount point 'gentoo' only if you use sync-type = squashdelta.

For improved output use sys-fs/squashfs-tools from the mv overlay.

It is recommended to put into your zshrc the line:
alias squashmount='noglob squashmount'"
