Description Shlomi Fish 2020-08-21 13:39:05 CEST

Description of problem:

Processing /etc/profile.d/lang.sh at autologin is time consuming / slow (~10 seconds) . I profiled it using the attached /etc/zshrc . Using this instead is much faster:

<<<
eval "$(perl -0777 -pE 's/[\r\n]/ /g;s#\A#export #' < "$HOME/.i18n")"
>>>

I am using this setup for vc autologin:

Note that zsh loads my bashrc.d/*.bash files too.

What's the output of the profiling?

it says that sourcing "/etc/profile.d/lang.sh" takes about 10seconds while all other operations take a few milliseconds at worst.

Shlomi, can you say whether this has always been the case, or is it new with Mageia 8? Also, does it just happen with autologin, or any login?

Assigning this to basesystem, no evident maintainer.

I do not recall it happening in mageia 7 or before.

This will require disabling autologin.
