[Pkg-zsh-devel] Bug#841048: zsh: temporarily removes symlink /usr/bin/zsh on upgrade

[Martin Steigerwald]

Package: zsh
Version: 5.2-5+b1
Severity: important

Dear Maintainer,

on upgrading zsh package temporarily removes symlink /usr/bin/zsh breaking
su, sudo -i (without -s /bin/zsh), as well as Plasma desktop login.

Depending on the upgrade duration for the packages to be upgraded it can
leave the system in this broken state for minutes even on SSD systems.

I think this is related to the fix for

zsh: removal leaves dangling symlink /usr/bin/zsh behind
https://bugs.debian.org/823730


Expected outcome: Keep system intact during upgrades.

Thanks,
Martin
