All --
The two threads about the new 64-bit defaults in /etc/mke2fs.conf worry me a bit.
http://www.linuxquestions.org/questi...ng-4175580324/
and
http://www.linuxquestions.org/questi...ed-4175580346/
Specifically, is it safe to run fsck on the existing 32-bit ext4 partitions on my system ?
I did not have any problems after the Friday May 20 Updates to Current but on the other hand, I've not run fsck since that update either.
Would it be wise to revert /etc/mke2fs.conf to the 32-bit default from before the update to Current before fsck is run ( i.e. before my next reboot, just in case fsck happens to run ) ?
tune2fs seems OK with the new /etc/e2fsck.conf file ( below ) and I've got no /etc/e2fsck.conf file, but does /etc/mke2fs.conf affect fsck ?
Thanks.
