In some embedded systems, users only use the ps
provided by the busybox. But the ps provided by
the busybox does not support the -eo option by
default. As a result, an error is reported when
the userdel is used. So add a judgment on ps.
If there is no ps -eo, traverse the process directly.
The error information is as follows:
# userdel xsl
ps: invalid option -- 'e'

run_parts currently exists in useradd and userdel, this commit mirrors
the functionality with groupadd and groupdel
Hook for group{add,del} to include killing processes that have group
membership that would no longer exist to avoid membership ID reuse.
