Sorta makes mon useless, doesn't it? :p
The funny thing is... I *HAVE* been able to delete before. It's odd... I
always can find someway to replicate this error -- just sometimes there are
more ways than one.
Thanks for the confirmation. I tried to trace exactly what was happening
when someone issued a delete command... but everything I can tell -- jumping
from file to file and routine to routine... it just looks like nothing vital
happens. A few if statements here... a little output there... but nothing
that should cause the system to halt. :(
Oh well.
Just a side note: in ip_vs_pcc.c, "Initializing" is spelled wrong and the
spacing is a little off. It's in the section that is executed at system
boot -- as the dmesg is built. Easy fix.
All the best --
Ted
