I'm having trouble with my /etc/network/interfaces file that is overwritten by every Preseed install.
I have found out that when I let the late_command crash and I manually enter some identifier in:
the one in /etc/network/interfaces stays there, so no overwriting from the target version in that case. The fix to place the following in the late_command doesn't fix it either:
cp /target/etc/network/interfaces /etc/network/interfaces
Any idea on how to fix this?
