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. > if you were using Linux with ext3/ext4 or Windows with NTFS. Especially your last example is really bad. It's quite common for Windows and NTFS to get completely messed. >> Why you need sysinstall AT ALL? > I am well capable of doing a textmode installation using console > commands only, so _I_ don't.

A new user 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.
