# mount-network-drive.sh — Mount a network share (SMB/CIFS or NFS) and add
|
||||
# it to /etc/fstab so it survives reboots.
|
||||
#
|
||||
# Usage:
|
||||
# sudo bash mount-network-drive.sh
|
||||
#
|
||||
# Supports:
|
||||
# - SMB/CIFS (Windows shares, Samba, NAS)
|
||||
# - NFS (Linux/NAS exports)
