What are advantages and disadvantages of building Arch Linux packages for custom repository directly on VPS versus on the PC + upload through rsync to public repo on VPS?

Ideally there's no difference if you follow the best practice for a shared repo and build things from a clean chroot: https://wiki.archlinux.org/title/Develo … ean_chroot
In some rare cases some build procedures might enable advanced features based on CPU instruction availability that might not be present in a potential target system, but one should consider that a bug of the build system/build instructions (unless your using -march=native from the get go -- which you shouldn't, assuming you have a wide variety of target architectures) but there's nothing that the VPS would inherently protect you from. So ideally you'd build from whichever system can get the build done faster and/or cheaper.

Does exist any safe way to sign built packages directly on VPS? I want to have all packages signed using my gpg key in my repository
