When running
extract_qnap_fw.sh
on a QNAP NAS, mounting something on/mnt
hides already existing mounts within/mnt
. A lot of file in/etc
are actually just symlinks to/mnt/config
, and/etc/passwd
is one of them. So when mounting a directory on/mnt
results in loosing access to all account information. I.e. any subsequent attempt to use sudo (or login to the system) fails.This change uses temporary directories (created using
mktemp
) to mount images in order to avoid the issue.
