Failed to edit crontab (linux Alpine) -

i faced error during cron manipulation under non-root account.

bash-4.3$ crontab -e crontab: must suid work 

here output on id command:

bash-4.3$ id uid=41532(fred) gid=41532(fred) groups=41532(fred),41532(fred) 

btw works root account.

the solution is:

apk add --update busybox-suid
