"umask 022" روی چه فایلی؟ (در نصب تک-لایو)

[dorfa]

۱. این توضیحات زیر میگه که باید umask  تنظیم کنیم. چه فایلی رو؟
منبع
Download the installer. Open a terminal in the folder and log in as root. Change the umask to 022 to make sure other users will have read-only access to the installed distribution
منبع: Warning about Unix permissions: Your umask at the time of installation will be respected by the TEX Live installer. Therefore, if you want your installation to be usable by users other than you, make sure your setting is sufficiently permissive, for instance, umask 002


۲. بدتر اینکه منبع اولی میگه 022 و منبع دوم میگه 002؟!
