I have a server configured with sftp jailed account(sftpxyz) under /chroots/sftpxyz

Did binding of /usr/sap/bac/LAE to /chroots/sftpxyz/LAE , where /usr/sap/bac/LAE is an NFS share coming from Isilon storage

To keep it persistent across reboot made an entry in /etc/fstab ,
/usr/sap/bac/LAE /chroots/sftpxyz/LAE none defaults,bind 0 0

df -h

kopisiloncl01:/ifs/data/sap/
100G 12G 87G 13% /usr/sap/

Problem:
The mounting of /usr/sap/bac/LAE is FAILING after the reboot.. Reason being, the NFS service starts after the mounting attempt of /chroots

Remounting root filesystem in read-write mode: [ OK ]
Mounting local filesystems: mount: special device /usr/sap/bac/LAE does not exist
mount: special device /usr/sap/bac/LAE does not exist
[FAILED]

Starting RPC idmapd: [ OK ]

Workaround: Currently, after the reboot of the server, i am manually remount /chroot/sftpxyz

Question:
1. How to come over this issue? If i change the boot order of NFS or chroots what will be the impact ?
