Hello Gentoo users

Have you tried to install Gentoo on the Raspberry Pi 5? I want to
buy one and set up budget home server on it.

How much average time it will take before I'll have working stage3 with running nginx, gitea, docker etc.? Will it take days or can I finish
setting up rpi server in one day?

I mean running Gentoo arm64 from official hat providing nvme support,
not microSD card.

Will compile times be similar to achieved on my old Lenovo ThinkPad
X220? If so, that would be acceptable for me.

Thank you, whiteman808

You may optionally choose to use the official binhost, in which case you
will avoid quite a bit of compilation. For example, nginx and docker are
both available as binpackages (but not gitea, which is not even stable
for arm64).

https://wiki.gentoo.org/wiki/Gentoo_Binary_Host_Quickstart

As usual with binpackages, this fully respects your USE flags (but not
CFLAGS) and transparently falls back to compiling from source for all
packages:

- without binary availability, or
- for which you prefer a specific USE flag lacking in binary
availability

Not clear to me if you want to just install the stage3 or do the usual install-customize-rebuild @system @world. I'll answer for the latter.

I have a Gentoo-based Rpi4, I cross-compile most of the packages so
can't provide numbers for comparison except for the few that I have to
compile natively due to crossdev issues, e.g.:

# qlop -mav git
dev-vcs/git-2.49.0-r1: 14′47″ average for 1 merge

# qlop -mav apache
www-servers/apache-2.4.63: 9′55″ average for 2 merges

For the Rpi4 I'd bet on days before you get a complete running system.
Rpi5 is just a bit more powerful but I'd go crossdev or binhost anyway.

In case you haven't seen yet, there are some Rpi guides on Gentoo: https://wiki.gentoo.org/wiki/Raspberry_Pi_Install_Guide https://wiki.gentoo.org/wiki/ARM

For the kernel I use the official raspberry tree and build it from source: https://www.raspberrypi.com/documentation/computers/linux_kernel.html#cross-compiling-the-kernel

Last but not least, crossdev:
https://wiki.gentoo.org/wiki/Crossdev

I use the Rpi4 as a headless dns server (pihole).

The RPi5 is quite a bit faster than RPi4, and none of the packages you're describing are particularly compile-intensive. Having an SSD will help quite a bit. Also, if you have a fan and a good power supply, you'll want to change the CPU governor from
the default "powersave", which limits the CPU clock speed to 1.5 GHz, to "schedutil", which gets you up to 2.4 GHz.

Mine has a USB3 SSD (probably not as fast as your nvme one) and schedutil governor. I do build everything from source, including some big packages like llvm/clang, and it's quite doable. Here's some build times for things you'll need:

app-containers/containerd: 2′02″ average for 1 merge
app-containers/docker: 2′23″ average for 1 merge
app-containers/runc: 43s average for 1 merge
dev-lang/go: 4′12″ average for 1 merge
dev-vcs/git: 2′23″ average for 17 merges
sys-devel/gcc: 1:34:41 average for 18 merges
www-apps/gitea: 3′59″ average for 1 merge
www-servers/nginx: 53s average for 1 merge

So I think you'll be fine. The largest part of build time will probably be building gcc, so if you use a binary package there, it will cut it down substantially.

For contrast, here are build times for some larger packages that you probably don't need. Definitely takes a while, but not days.

app-office/libreoffice: 4:21:27 average for 1 merge
dev-lang/rust: 1:34:12 average for 20 merges
llvm-core/clang: 2:24:44 average for 6 merges
llvm-core/llvm: 2:26:21 average for 6 merges
net-libs/nodejs: 4:25:39 average for 18 merges
sys-devel/clang: 2:26:35 average for 10 merges
sys-devel/llvm: 2:23:51 average for 14 merges
www-client/firefox: 2:20:08 average for 36 merges
