pdsh is a great tool... but with 1500 systems, I bet he knows about it.
DSU should be fixed, of course!
A critical or high impact release update for BIOS/firmware *.BIN files
should cause the Dell magic internal process to update the DSU repo!
Yes the bosses likely decided once-per-whatever is good enough, but clearly
it's not (good enough). All distributions have the concept of
security/severity for packages and updates in repositories; utilize those
options. Keep your stable once-per-whatever but give these high impact/high
profile updates some legs to move out more quickly and effectively for your
Dell customers.
DSU has grown for the better... continue the growth in a positive direction.
Thanks
