EDIT: seems this is a bug in the at-3.2.4 changes see the upstream bug
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1004972
and will probably be fixed in at-3.2.5
Anyone else having trouble with the at package?
If I update to at-3.2.4-1.1, restart at and test an at command I find the command doesn't execute at the specified time. Instead it executes when another at command is entered.
If I revert to at-3.2.2-1.1 and restart then commands execute at the expected time.
I see the same behaviour in archlinux x86_64, armtix aarch64 & manjaro aarch64.
I used strace to look at what the two versions do at the expected time; it looks like at-3.2.4-1.1 gets a wakeup at the expected time, but doesn't seem to execute the child process as is done in at-3.2.2-1.1, but I am not an expert.
at-3.2.2 expected time is 11:21:00
