Actually, there's no need to remove the Ubuntu packages - the two quite
happily coexist, it would seem - but there's not much point having both,
I suppose.
I can't see anything that in tlmgr that allows you to retrospectively
"plumb everything in", so if you haven't been upgrading and customising
packages all over the place it's probably frankly easiest to just
uninstall TL'08 and have another go! Ticking the little box this time...
However, since this is sort of the "nuclear option", I'd give it a few
hours in case someone with more know-how than me has a better idea: this
will certainly do it, but there may be a more elegant way that involved
less downloading...
Hope that helps,
David
PS. I sim link (which mine don't seem to be, which is rather surprising)
is a little file system trick that looks like a file, but in fact just
points to another. (Almost) anything that you "do to the sim link" you
in fact do to the file it points at. It's a bit like a reference in C++.
As to how it differs from a hard link, I am afraid that I don't know!
Sim links are typically used to make a directory structure conform to
several different expectations without introducing multiple versions of
files; for example, many executable files live in /usr/bin (and the OS
expects them there), but if programme A wants to find foo in
/opt/bar/bin, for instance, then putting a sim link to foo in
/opt/bar/bin satisfies the OS and programme A without multiple real
copies of foo being created.
Make sense?
