I don't think so.
I've installed SLS 0.98p5 obtained from the tsx-11 mirror that Lee set
up in:
doc.ic.ac.uk:/pubic/computing/operating-systems/Linux/tsx-11.mit.edu
and the installation worked correctly. The only problem I encountered
was that the install.end files were compressed (so were renamed
install.end.Z) and the 0.99 kernel sources wouldn't fit on disk a4 along
wth 0.98p5 sources.

You are quite right that, some time ago, we didn't have mirror deletes
enabled but I asked Lee to enable deletes because the old files were
redundant and confusing. Another problem was that some files in the
mirror were symbolic links pointing outside the area accessible by ftp.
I pulled SLS up to Aberdeen in the last couple of weeks and as far as I
can see the tsx-11 mirror at doc.ic.ac.uk is working correctly.

This is not true if mirror deletes are enabled is it?

Yes, we are doing the mirror to avoid unneccessary duplication of ftp to
tsx-11 from UK sites. I couldn't work out what the extent of the overlap
was between funet and tsx-11 so we are mirroring both. These archives are
a genuine goldmine of Linux material and are accessible at several sites
in the UK including doc.ic.ac.uk
