# Arch / Void differences

i just got an arch glibc (`2.38-7` pacman) to compare to ours (`2.38_4` xbps), so i'mma just post some findings of differences here, slowly growing this post as i figure out what to look for.

## `file` output

## "red objects"

since i have no idea which of those are flags and which are herrings, here are some things i'm noticing so far:

* we're missing `.gnu.version_r`,  which "shall contain required symbol version definitions" according to [LSB](https://refspecs.linuxbase.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/symversion.html)


and: **look down**, smarter people than me are contributing to this list, but i try to keep this updated as we figure things out here :)
