I successfully updated from 10.14.1 to 10.14.2 on my Mojave HFS partition by creating a full installer USB ---> in place upgrade installation.  This avoided the missing frameworks/app opening problems associated with the updater script discussed above...

 

* Can use either @dosdude1's macOS Mojave patcher tool or @crazybirdy's MBR-EasyInstallerMaker script to make USB installer from full 10.14.2 app
* Boot system to USB installer and target the 10.14.1 partition to perform upgrade install
* After upgrade completes, boot system to Mojave in single user mode to patch/replace com.apple.telemetry.plugin (eg with mojave2core script).  Can also replace legacy kexts from High Sierra if overwritten by update

 

eg in single user mode, type the following commands followed by <Enter> after each line ...

fsck -fy
mount -uw /
/usr/bin/mojave2core
cp -R /Volumes/USB/Kexts/* /System/Library/Extensions  //Assuming you put legacy NVidia/other needed kexts in "Kexts" folder on your USB 
touch /System/Library/Extensions && kextcache -u /
reboot
