I've built 3 *.iso images:
My suggestion is to put your project under version control and compare the changes between methods!
1. Updates integrated by HFSLIP -(next)-> AddOns integrated by RVM Integrator 1.6
2. Updates integrated by HFSLIP -(next)-> AddOns integrated by nLite 220.127.116.11 (with "classic setup" enabled)
3. Updates and AddOns integrated by HFSLIP K v3
Then installed XP (on VMware) from each image and everytihng went well - no errors, no missing files, etc.
There were some files in HFSLIP *.iso that were not in RVM or nLite *.iso:
(last three not related to Printer UpdatePack)
RVM and nLite packed many files which were unpacked in HFSLIP:
*.inf -> *.in_
*.dll -> *.dl_
*.cat -> *.ca_
I think the best method is HFSLIP -(next)-> RVM Integrator -
- it's a little bit longer then RVM Integrator -(next)-> HFSLIP (looking ahead in the long term),
but I dont have to worry about overwriting some files with older ones.
