Hi, in the arch repos, there is a very useful tool called pacredir.
It helps sharing pacman packages in the local network, so if another computer in your network already has package x, you won't have to redownload it, it will be transfered from the other computer in your network, which is much faster. This is great for people like me with slow internet connection.
But pacredir in it's default configuration is incompatible with Manjaro branches.
You can read more about the issue here:
To avoid this issue, we have to add a file to the package in a manjaro specific version:
[Service] BindReadOnlyPaths= BindReadOnlyPaths=/var/cache/pacman/pkg:/run/pacserve/pkg
Also, as an alternative, the arch maintainer 'could think about handling this at build time'.
Does someone of the Manjaro team want to maintain our own pacredir package?
