[It's quite hard to move back to aac(4) as that requires fstab update
[ aacdu0 -> aacd0]
 and instant reboot, because we use quotas and quotacheck looks into /etc/fstab.
Such preparations as fstab update and commenting out load_aacu="YES" will give
discrepancy between fstab and actual mount points.]

I will try anyway. Thank you for your help.
