Indeed. We use NIS. Support for NIS was removed in the el7 installer. Rejoyce!

Indeed. Have been using kickstart installs for years. CD/DVD kickstarts,
PXE-network-booted kickstarts, now mostly USB-flash-booted kickstarts.

In our environement we cannot do a one-size-fits-all kickstart,
so possibility to configure NIS during installation was quite handy.
Now it becomes a post-install step - login as root, run authconfig.

Actually now, due to this "must create, then delete fake user, which will also use a UID
colliding with our historic UID allocation scheme", non-kickstart vanilla
installer is pretty much useless.

The kickstart disk partitioning tool is even dumber than they new GUI tool,
only useful for "one-size-fits-all" cases where you also do not mind accidentally
deleting the contents of all disks. (yes, open the machine, disconnect disks,
install, reconnect disks, close the machine, thanks, but no thanks).

At least the el7 installer does not overwrite the bootloader of the *installer* disk
and seems to correctly install the boot loader for raid1 mirrored slash partitions.

P.S.

I keep banging about all this stuff because over the last 20 years all I see
is each new installer only reluctantly fix a few of the old bugs, but consistently
add new "features" which are not improvements.
