Operating System: Rocky Linux 9.4 (Blue Onyx)

Might be an issue with your host, this looks similar to #352

What's the output of the following commands?:

$ docker run -it alpine
/ # ls -al /var/spool
/ # rm -rf /var/spool/cron

[TheCrockett]

Seems like it works

[root@docker51 ~]# docker run -it alpine

Any update/resolution here?

[adminas8dev]

# cd /var/spool/cron/
# rm -fr crontabs
# mkdir crontabs
mkdir: can't create directory 'crontabs': Invalid argument

For some reason, mkdir cannot create crontabs dir, but any other dirname works fine..

Also if the "Backing Filesystem: zfs" is not zfs, then this problem goes away..
