Here is what I got (omitting those that appeared to have both 'ext4' and ext4dev'): /sbin/quotacheck ext4dev /sbin/quotaoff ext4dev /sbin/quotaon ext4dev /usr/bin/quota ext4dev /usr/sbin/convertquota ext4dev /usr/sbin/edquota ext4dev /usr/sbin/repquota ext4dev /usr/sbin/rpc.rquotad ext4dev /usr/sbin/setquota ext4dev /usr/sbin/warnquota ext4dev So I'm guessing those (all quota related) need updating. Don't think this has anything to do with my 'issue', however. Anyway, I can mount manually for now. Sorry I couldn't quickly figure out what was doing this..... tom -- Tom London -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
