aliases.db: setuid sticky fifo (named pipe)
norsu:/etc# rm aliases.db
rm: remove aliases.db', overriding mode 5604? y
rm: aliases.db: Operation not permitted

How to get rid of this file? Is it necessary to use some ext2-debugging tool?

Corruption happened when I tried Triton BM-DMA with BigFoot 2.5G hd. Others, does this hd work well in DMA mode?
