I'm about to do a system wide update of recommended patches on
2.6, 7 and 8 boxes, plus possibly Y2K patches if necessary.
Before I wade in with both feet, are there any known
"repercussions" of these patch clusters?
For example, a couple of years ago i was doing something
similar to some 2.6 boxes and after the alleged "upgrade" we
found that the email had stopped working, as the recommnded
patches included an "upgrade" from sun's sendmail to a quasi-
public domain sendmail version, and now none of the original
config files were compatible, the situation being "complicated"
by the fact the upgrade merely dumped on top of the original
binary rather than renaming/moving it first, and the backout
didn't do the trick! Subsequently I was left with a steep
learning curve in sendmail configuration files and a lot of
unplanned for work!
So - any *y traps like the above likely does anybody know
with recommended patches for 2.6, 7 & 8 (and Y2K for 2.6 ?)
