Good morning and Merry Christmas :) ,

so I am making an server on an old HP Compaq dc5700 workstation with hardened sources and SElinux and I don't know what profile would be the best. I'm struggling between a multilib and no-multilib profile.
As far as I know, no-multilib means no 32-bit support. I plan to use the server for NAS, TeamSpeak, Minecraft, web and might expand it to other applications.
Are there 32-bit only applications that I could be using in the future? Is it safe to choose no-multilib or is multilib by far better?

A friend told uses webmin to manage his server. Are there alternatives that are better suited for Gentoo you can recommend? :)

Additionally, I want to try the new Gold linker, but the Wiki says that it was known to break to grub2. Does breakage with ld.gold still occur to some packages or is it safe for system wide use?

The workstation also has a Broadcom TPM. Can I use it somehow?

You should avoid the multilib profiles. You can therefore use 32-bit applications by playing with the abi_x86 flags.

Webmin is an awful gaping security hole for lazy admins. You should take the time to learn to manage your system by CLI (ssh is all what you need). Your configuration files will thank you.

I don't know the gold linker. But do you really need it ? I suggest you to start with the standard tools, and consider, if you want again, migrating later, when you are comfortable with your system.

I think you can, if the kernel support it.

gold works fine, I've been using it for years on multilib, non-multilib and x86 machines with no issues.

You can switch to a multilib profile to no-multilib without reinstalling, but not vice-versa.

Note that if you go no-multilib, there is no way to run 32-bit programs on it without reinstalling or adding a 32-bit chroot install. That's why those ABI flags are p.use.masked, and no, unmasking them manually is not enough.

+1 To this, I've also been using it on multiple systems since 2012 without issues.
