I really don't think that's wise -- there's more to filesystem choice than
stability and efficiency.  For example, at one stage I maintained an
actively-used partition formatted as fat32, despite its lousy performance
in linux -- because it was shareable between Win32 and linux when
dual-booting. Reducing filesystem choice has many side-effects.

PS: if I recall correctly, Reiserfs did have an issue at one stage where
it was liable to data loss.  In 2001/2002 (this may have been fixed since
then), Reiserfs wasn't a true journalled filesystem -- metadata was
journalled, but file contents were not.  I haven't experienced it myself,
but I've heard reports of corruption and data loss due to this.

'Reiserfs has the added problem that you may have garbage in the contents
of your file if it was in the process of being modified at the time of a
crash.'

Has that been fixed?
