To all respondents on this topic whose time and commentary I do
appreciate, as well as the SL Fermilab/CERN support/porting/development
team:
Supposedly, SL6x is kept "current". I seem to find the necessary
packages on RHEL6 as displayed in this thread, but these do not seem
available on SL6x, despite RHEL6 being "Linux / open source / GPL source
licensed". Are these packages proprietary or not allowed in he USA (in
the latter case, the CERN EU repository should have these)?
If one needs repo for SL6 from
http://yum.postgresql.org/repopackages.php#pg93, why is this dependency
not made clear? I am not complaining about the merry chase -- having
experienced this many times before due to packaging inconsistencies --
but this is a massive waste of time, and even more so if I assign a
research student to this sort of thing (I do not have any postdoctoral
fellows at this time).
This is NOT a question of support; it is a question of just how much of
RHEL (TUV that evidently now is allowed to be mentioned rather than
hidden) is reflected in SL (or for that matter CentOS that is a wholly
owned/controlled subsidiary of Red Hat).
