1Password on Asahi Linux

Recently I decided to dual-boot Asahi Linux on my Mac Mini, and one application I use heavily is 1Password.

To my disappointment, I discovered that while 1Password does provide builds for ARM, they don't have any deb/rpm packages prepared, and there's only a tarball available.
And well that just won't fly, I very much want to have it packaged and manageable with the rest of the system.

So my workaround is to repack the RPM with rpmrebuild, replace the application files with the ones from the tarball and change the package architecture to aarch64.

To start of, lets install rpmrebuild and download the Fedora RPM and the ARM tarball:

sudo dnf install rpmrebuild
cd ~/Downloads
wget https://downloads.1password.com/linux/rpm/stable/x86_64/1password-latest.rpm \
     https://downloads.1password.com/linux/tar/stable/aarch64/1password-latest.tar.gz
     ```
tar -xf 1password-latest.tar.gz

Now, one issue I ran into while doing this, is that rpmrebuild detects that the current running architecture and the RPM we're building from are different, and so tries to use setarch x86_64 when it runs rpmbuild which fails on an aarch64 environment.

It's hacky, but I didn't find another option than to modify rpmrebuild to not do that in /usr/lib/rpmrebuild/rpmrebuild.sh (line 204 in the current version / function CheckArch):

 case $pac_arch in
 "$cur_arch")
         change_arch="";;
 noarch)
         change_arch="";;
 '(none)')
         change_arch="";;
 *)
         #change_arch="setarch $pac_arch";;
         change_arch="";;

I commented out what the catch-all was doing and just set change_arch to "" like the rest, this got it to work, even it's ugly as hell.

Then we should be ready to build our modified package (replace the version in the path with the one you got):

rpmrebuild \
    --package \
    --change-files 'rm -rv "$RPM_BUILD_ROOT/opt/1Password" && cp -rv ~/Downloads/1password-8.10.68.arm64/ "$RPM_BUILD_ROOT/opt/1Password"' \
    -f 'sed -e "s/x86_64/aarch64/g"' \
    1password-latest.rpm

When it's complete you should have a result: /home/lochnair/rpmbuild/RPMS/aarch64/1password-8.10.68-1.aarch64.rpm line at the end showing where to find the resulting rpm you can install.
