can you please give an example how it may render unbootable system?

For what i know and ever used (ext2,ext3,reiserfs,rarely NTFS, UFS) 
UFS is the only one that never failed. It is always recoverable, with few 
lost files worst case.

I recommend you to read a paper about softupdates to understand why they 
are so good.

The only problem with millions of files may be long fsck. but not THAT 
long, and FreeBSD doesn't crash every day.

Especially your last example is really bad. It's quite common for Windows 
and NTFS to get completely messed.

A new user will never do anything mission critical on system he/she don't 
yet learned isn't it?

After learning sysinstall is no longer needed.

Anyway it's not bad to add this to sysinstall, i'm only suggesting you 
that it's probably low priority task to developers.
