O padrão é de fato exec
, mas usar a opção user
implica nas seguintes opções:
- noexec
- nosuid
- nodev
Como explicado em man mount
:
user Allow an ordinary user to mount the filesystem. The name of the
mounting user is written to the mtab file (or to the private
libmount file in /run/mount on systems without a regular mtab)
so that this same user can unmount the filesystem again. This
option implies the options noexec, nosuid, and nodev (unless
overridden by subsequent options, as in the option line
user,exec,dev,suid).
