What's really wander me, why is here difference between `mount' and `mount -p' output on my system. It looks like `-p' option should be cosmetic one...

So, we know why here is difference between my and your `mount -p' outputs! (BTW, why both values are default?!) And here is some conflict of interests: it is god to allow useres restore their files from snapshots without my help (and it is require visible snapshots), but it is very annoying output in security checks... And why output of mount depends on visual option? I need to read mount sources. --=20 // Black Lion AKA Lev Serebryakov
