how can one configure e2fsck to run periodically let's say every 30 mounts at boot?
…and no it doesn't run at every boot:
[root@MyBookWorld init.d]# cd /
[root@MyBookWorld /]# ls
bin etc lib lost+found mnt opt root shares tftpboot usr
dev home linuxrc man none proc sbin sys tmp var
[root@MyBookWorld /]# dd if=/dev/zero of=/swapfile bs=1M count=1000
1000+0 records in
1000+0 records out

[root@MyBookWorld /]# mkswap /swapfile

[root@MyBookWorld /]# swapon /swapfile
[root@MyBookWorld /]# umount /dev/md4
[root@MyBookWorld /]# e2fsck /dev/md4
