Hello Jacek,

Qserv already need some rpm dependencies when it's installed. So packaging
it as a rpm would only require the sysadmin to install a (few) rpm more.
Qserv, once installed with root account, could then run under user account
named qserv, and wouldn't require no more root privileges, (Mysql and
Apache httpd are usually installed this way on linux boxes). This could be
an interesting intermediate solution, but root account would still be
needed at bootstrap.

rpm would be an easy solution to install Qserv, but it also require to
check that all qserv dependencies, that are compiled during automated
install procedure, are also available as rpm, and with compatible
versions. I think it also required to build a rpm for xrootd patched
version, and maybe for scisql (unless they can be embedded in Qserv rpm
?).

So it seems there's some job to build this rpm. I can first study this if
you want, in order to list all the tasks needed to do this. Maybe a
comparison with a eups full install could be also usefull ?

Have a nice day,

Fabricea

P.S. : Thanks for sending the coordinates of yesterday meeting, but, even
if i was very interested,  i wasn't able to come, sorry. I will be avaible
next tuesday.
