Does ext2 based on MTD acceptable for Embedded Development?

Hi,

Although I made ext2 on RPXlite DW board and worked,I
still want to consult with you such a question.Dose
ext2 filesystem besed on MTD a acceptable option?
Compared with JFFS2 and Cramfs,it's really hard to
create on FLASH.I mean the case of 30MB filesystem.I
just did succeed once but the performance was
unacceptable at all.Boot time could last
3'39"00,longer than 2-3 times than other
filesystem.Where did I go wrong,in method itself or
some detailes?

or

root@172.16.115.12:/# cp -a /test/tmp /mnt

Often after that system would hang when using
'reboot'.A hard reset could see kernel crashed by 'no
init' message.

Thanks in advance!
