I observed the issue that IPCop is unable to install on storage devices
which hold non-IPCop partition data already during my intensive testing
with the 1.9.x line, but it seems that this issue is still with actual
release. I got this issue also reported from some friends who use IPCop;
actually a friend repoteded it to me who wanted to use a HD which was
formerly partitioned by M0n0wall.
In all cases it helped to wipe the partion data with something like:
dd if=/dev/zero of=/dev/[h|s]da bs=1k count=1000
but I wonder why the IPCop installer cant correctly partion itself or
wipe the storage device 1st - although it claims to do so with its
warning .... :-P
its always troublesomely to 1st do the wiping with a LiveCD - specially
when the firewall hardware is an embedded system with a flash where you
need to disassemble the whole hardware in order to pull the CF ...
