The /etc/fstab states it's a normal ext2 format which
is in the kernel - so I don't think that should be a
problem.
Something else which may be weird: there is NO
/boot/initrd* file on the laptop - which I found was
created by the kernel image (a standard 2.4.18-686
image) on this computer I use myself - could this be
the problem?
I found there is a document about this initrd but I
find it hard to follow - especially on the part about
/linuxrc which I can't find - How can I get the
/boot/initrd* file created (if it's indeed needed
there) ? Can't I simply run a program for that ??
I find it odd that if the complete compilation setup
can be done without manual stuff, this part has to be
done without any help, just like that !
I hope you can tell what to do - it's some manual
there all right and it looks like it's some work
allright
thanks very much,
Joris
