# Notes:
# If we use 'rw' as part of -o, by default, CIFS mounts are owned by root unless explicitly configured otherwise.
# So, writing on that share would require 'sudo', e.g. 'sudo mkdir myfld' due to how ownership and permissions are managed.
# Resolution: Specify the ownership and permissions explicitly when mounting the share with:
#   rw,uid=$(id -u),gid=$(id -g)
#     uid=$(id -u) sets the user ownership of the mount to your current user.
#     gid=$(id -g) sets the group ownership of the mount to your current user's group.
# Permission Problem: The file_mode and dir_mode options control permissions for files and directories.
#   file_mode=0644: permissions for files in the mounted filesystem.
#   0: No special mode bits (no setuid, setgid, or sticky bits).
#   6 (Owner): Read (4) + Write (2) = 6.
#   4 (Group): Read (4).
#   4 (Others): Read (4).
#   This means: Owner can read and write files. Group and Others can only read files.
#   dir_mode=0755: permissions for directories in the mounted filesystem.
#   0: No special mode bits.
#   7 (Owner): Read (4) + Write (2) + Execute (1) = 7.
#   5 (Group): Read (4) + Execute (1).
#   5 (Others): Read (4) + Execute (1).
#   This means: Owner can read, write, and access directories. Group and Others can read and access directories (but cannot modify them).
